Xamarin UI test issue related to permissions Popup in Android

Hi,
Am using Xamarin forms and writing UI Test for Android using Xamatin.UI test frame work.
Using Android 8.1(Oreo)
Got blocked one Place : when using camera is asks for OS based popup, it contains "Deny" and "Allow" it was not found in Repl to identify the UI component.
Attached image.

How to handle this situation writing UI test related to camera.

CameraIssue

FYI:
public static IApp StartApp(Platform platform)
{
if (platform == Platform.Android)
{
var installApp = ConfigureApp.Android.InstalledApp(apkName);
return installApp.StartApp();
}
}

Thanks & Regards,
Siva
