Xamarin Android notifcation - turn on screen

I'm trying to create a notification thats turns on the screen when it happens(same as calls/ sms)

I have this

            public void NotifyWithIntent(string title, string text, DateTime time, Type intentTarget) {
            int id = 0;
            var intent = new Intent(Application.Context, intentTarget);
            Android.App.Notification.Builder builder = new Android.App.Notification.Builder(Application.Context).SetContentTitle(title).SetContentText(text).SetSmallIcon(Resource.Drawable.icon2).SetAutoCancel(true).SetSound(RingtoneManager.GetDefaultUri(RingtoneType.Notification));

            NotificationManager notificationManager = Application.Context.GetSystemService(Context.NotificationService) as NotificationManager;
            Intent notificationIntent = new Intent(Application.Context, intent.Class);
            var pendingIntent = PendingIntent.GetActivity(Application.Context, 0, intent, PendingIntentFlags.UpdateCurrent);
            builder.SetContentIntent(pendingIntent);
            builder.SetWhen(RepositoryService.TimeMillis(time));
            builder.SetPriority((int)NotificationPriority.Max);
         builder.SetCategory(NotificationPriorityCategory.Calls.ToString());
            Android.App.Notification notification = builder.Build();
            notification.Defaults |= NotificationDefaults.Vibrate;
            notificationManager?.Notify("", id, notification);

What can i add to get the screen to turn on when the notification occurs ?

Add ACQUIRE_CAUSES_WAKEUP to your wake lock flags:

var powerManager = (PowerManager)GetSystemService(PowerService);
var wakeLock = powerManager.NewWakeLock(WakeLockFlags.ScreenDim | WakeLockFlags.AcquireCausesWakeup, "StackOverflow");
wakeLock.Acquire();
await Task.Delay(1000);
wakeLock.Release();

Wake lock flag: Turn the screen on when the wake lock is acquired.
