如何在 Xamarin.Forms android 中向用户请求自动启动和省电模式（无限制）的权限？

Question

I am creating an application for myself, and I need my service to work when the device is rebooted. I did it here is my code.

namespace Corporate_messenger.Droid.Broadcast
{
    [BroadcastReceiver(Name = "com.companyname.corporate_messenger.BootReceiver", Enabled = true, Exported = true)]
    [IntentFilter(new[] { Android.Content.Intent.ActionBootCompleted })]
    public class BootReceiver : BroadcastReceiver
    {
        private void Start1(Context context)
        {
            Intent mycallIntent = new Intent(context, typeof(MainActivity));

            mycallIntent.AddFlags(ActivityFlags.NewTask);

           


            Android.App.Application.Context.StartActivity(mycallIntent);
        }
        public override void OnReceive(Context context, Intent intent)
        {
            try
            {
               

              
                var intentService = new Intent(context, typeof(NotoficationService));
                if (Android.OS.Build.VERSION.SdkInt >= Android.OS.BuildVersionCodes.O)
                {
                    SpecialData.RestartResponse = true;
                    context.StartForegroundService(intentService);

                }
                else
                {
                    context.StartService(intentService);
                    // Flag_On_Off_Service = true;
                }
            }
            catch(Exception ex)
            {
                Log.Error("MyLog", ex.Message);

            }


        } // OnReceive
    }
}

I also requested permissions to work with folders and microphone. My cod - Permission

 public async Task Permission()
        {
            
            var PermissionsStrorage_Write = await Permissions.CheckStatusAsync<Permissions.StorageWrite>();

            var PermissionsInternet = await Permissions.CheckStatusAsync<Permissions.NetworkState>();

            var PermissionsStrorage_Read = await Permissions.CheckStatusAsync<Permissions.StorageRead>();

            var PermissionsRecord = await Permissions.CheckStatusAsync<Permissions.Microphone>();
            if (PermissionsInternet != PermissionStatus.Granted)
            {
                PermissionsInternet = await Permissions.RequestAsync<Permissions.NetworkState>();

            }
            
            if (PermissionsRecord != PermissionStatus.Granted)
            {
                PermissionsRecord = await Permissions.RequestAsync<Permissions.Microphone>();

            }
          
            if (PermissionsStrorage_Write != PermissionStatus.Granted && PermissionsStrorage_Read != PermissionStatus.Granted)
            {
                PermissionsStrorage_Write = await Permissions.RequestAsync<Permissions.StorageWrite>();
                PermissionsStrorage_Read = await Permissions.RequestAsync<Permissions.StorageRead>();
            }
            if (PermissionsStrorage_Write != PermissionStatus.Granted && PermissionsStrorage_Read != PermissionStatus.Granted)
            {
                return;
            }
        }

Result code: But I ran into a problem, which is that for my service to work correctly on some devices, two checkboxes are required. Here's a picture

Now I don't understand how to ask the user about these permissions so that he doesn't have to go into the settings himself. Perhaps the application could open this page on its own.Basically, this problem occurs on xiaomi phone. At the moment I am writing an application for android. But xamarin allows you to write code for iOS, so in the future I will also add such functions there.

here is the answer to this question

 private void SetSetting()
        {
           
            // Manufacturer (Samsung)
            var manufacturer = DeviceInfo.Manufacturer.ToLower();
            switch (manufacturer)
            {
                case "xiaomi":
                    SetPermission("com.miui.powerkeeper", "com.miui.powerkeeper.ui.HiddenAppsConfigActivity");
                    break;
                case "huawei":
                    SetPermission("com.huawei.systemmanager", "com.huawei.systemmanager.appcontrol.activity.StartupAppControlActivity");
                    break;
                case "samsung":
                    if(Battery.EnergySaverStatus == EnergySaverStatus.On)
                        SetPermission("com.samsung.android.lool", "com.samsung.android.sm.battery.ui.BatteryActivity");
                    break;
            }
           
        }

        private void SetPermission(string param1,string param2)
        {
            try
            {
                Intent intent = new Intent();
                intent.SetComponent(new ComponentName(param1, param2));
                // intent.SetComponent(new ComponentName("com.miui.securitycenter", "com.miui.appmanager.ApplicationsDetailsActivity"));
                intent.PutExtra("package_name", PackageName);

                StartActivity(intent);

            }
            catch (Exception anfe)
            {
            }
        }

Only I just don't understand how to find out the status of the flag
