Xamarin Native module

I am looking for sample module in Xamarin native that utilizes google firebase for push notification. The push notification have to be handled in the onMessagereceived for when the application is in foreground or background. There are quite a few samples that show how this is done, but what I like is to group/handle the notification exactly like what's app does. Each push notification will have an identifier in the payload to identify to which group does a message belong and a username along with the message body. Unseen notifications would be grouped by the group Id and the messages would be sorted by received time. Messages from the user x would be stacked under x in chronological order, again just like what's app. Each notification summary will have an intent to launch a specific activity when clicked thus handling the notifocation The deliverable is a visual studio project with the respective android and ios projects. If you have done this before it should be something really fast to do. If you havent grouped organized notifications before I do not think you are the right person. Looking for a quick delivery.
