Android OneSignal，从通知中打开特定片段

Question

I want to directly open the specific fragment through using title from notification.

In my BaseApplication class I tried this code and i was able to set the flag as i wanted.

   OneSignal.setLogLevel(OneSignal.LOG_LEVEL.VERBOSE, OneSignal.LOG_LEVEL.NONE);

        // OneSignal Initialization
        OneSignal.initWithContext(this);
        OneSignal.setAppId(ONESIGNAL_APP_ID);

        OneSignal.setNotificationOpenedHandler(result -> {
            Log.d("TAG", "notificationOpened: " + result.toString());

            if (result.getNotification().getTitle().toLowerCase().equals("first")) {
                fromNotifFlag = "first";
            } else if (result.getNotification().getTitle().toLowerCase().equals("second")) {
                fromNotifFlag = "second";
            }
        });

I used this flag to open the fragment in MainActivity(onCreate).

 if (BaseApplication.fromNotifFlag.equals("first")) {
            Navigation.findNavController(getCurrentFocus()).navigate(R.id.action_mainfragment_to_secondFragment);
        }

        if (BaseApplication.fromNotifFlag.equals("second")) {
            Navigation.findNavController(getCurrentFocus()).navigate(R.id.action_mainfragment_to_secondFragment);
        }

It didn't work for some reason. How can i listen the notification and open a specific fragment?

The code i shared is actually working but i used the second part in my mainFragment instead of mainActivity.
