[Firebase_messaging] Showing different notification tray although messages are sent by the same person.

[Prajun2010]

For a foreground notification, I'm using the flutter_local_notification package to show heads-up notifications. Over here, I have the option to assign a message notification id that enables showing messages on the same notification tray sent by the same users.

The main point is, I've been looking for a solution to display messages on the same notification tray sent by the same users when an app is terminated or in the background state, but I couldn't find it.

Currently, on the notification drawer

Actually wanted like this.
