Perhaps this:

or there are several push notification extensions available...

My Newbie Assumption:

You may be able to use One Signal Push notification as well (using extension).

If new message from sender got updated in database, then trigger one signal notification towards receiver as like 'You Got a New Message from Sender A'.

For that you may have to assign each One Signal ID to each user.

If this idea is complicated, then go with easy ideas.
