Please make sure Messenger app has notification permissions. On Android, go to Settings -> Apps -> Messenger -> Notifications and make sure that Block All is not checked.

Just add this to the activity:

using Newtonsoft.Json.Linq;
...
      activity.ChannelData = JObject.FromObject(
      new
      {
          notification_type = "REGULAR"
      });
