  <p>I'm using this code to display it. </p>
  
  <pre><code>void SendNotification(string messageBody)
      {
          var intent = new Intent(this, typeof(MainActivity));
          intent.AddFlags(ActivityFlags.ClearTop);
          var pendingIntent = PendingIntent.GetActivity(this, 0, intent, PendingIntentFlags.OneShot);
          NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                                                                  .SetContentTitle("FCM Message")
                                                                  .SetSmallIcon(Resource.Drawable.icon)
                                                                  .SetContentText(messageBody)
                                                                  .SetChannelId("my-chanel")
                                                                  .SetAutoCancel(true)

                                                                  .SetSound(); 
  
          var notificationManager = NotificationManager.FromContext(this);
