How to know if user has disabled Picture in Picture feature permission?

PermissionUtils.kt

const val ACTION_PIP_SETTING = "android.settings.PICTURE_IN_PICTURE_SETTINGS"

@RequiresApi(Build.VERSION_CODES.O)
fun AppCompatActivity.hasPictureInPicturePermission(): Boolean {
    val appOps = getSystemService(Context.APP_OPS_SERVICE) as AppOpsManager
    val uid = android.os.Process.myUid()
    val mode = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
        appOps.unsafeCheckOpNoThrow(AppOpsManager.OPSTR_PICTURE_IN_PICTURE, uid, packageName)
    } else {
        @Suppress("DEPRECATION")
        appOps.checkOpNoThrow(AppOpsManager.OPSTR_PICTURE_IN_PICTURE, uid, packageName)
    }
    return mode == AppOpsManager.MODE_ALLOWED
}

@RequiresApi(Build.VERSION_CODES.O)
fun AppCompatActivity.requestPictureInPicturePermission() {
    val packageUri = Uri.parse("$PACKAGE$COLON$packageName")
    val intent = Intent(ACTION_PIP_SETTING, packageUri)
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
    startActivity(intent)
}
