Implement Firebase In-App Messaging in Ionic

Recently I show a new option in the firebase console called "In-App Messaging" so I wondered is there any option in ionic plugin to implement the same so I go through the each and every firebase plugin like and

But can’t find any option related to this so I tried with installing the fcm plugin just need to check in case its automatically managed by firebase libraries. But when I create an In-App campaign and checked anything happens or not but nothing is happening.

so do you guys have any idea how its work ? I understand its still in beta mode so it will take time to reflects in ionic plugin.

I think you got answer from here
