You can try this:

val packageManager: PackageManager = viewLayer.activity.packageManager
val intent = Intent(Intent.ACTION_VIEW, Uri.parse("geo:0,0"))
val resolvedInfoList: List<ResolveInfo> = packageManager.queryIntentActivities(
    intent,
    PackageManager.MATCH_DEFAULT_ONLY
)
for (resolvedInfo in resolvedInfoList) {
    val packageName: String = resolvedInfo.activityInfo.applicationInfo.packageName
    val appName: String = resolvedInfo.activityInfo.applicationInfo.loadLabel(packageManager).toString()
    val launcherIcon: Drawable = resolvedInfo.activityInfo.applicationInfo.loadIcon(packageManager)
}
