                    Manifest.permission.ACCESS_FINE_LOCATION
                )
                != PackageManager.PERMISSION_GRANTED
            ) {
                ActivityCompat.requestPermissions(
                    it,
                    arrayOf(Manifest.permission.ACCESS_FINE_LOCATION),
                    10001
                )
            } else {

            }
