Hi @Marcus De Santis ,
There are plans to include an unread message count to the Chat SDK. However, it's in the preliminary stages of discussion. If you could with a comment down below, further elaborate on your use case / scenario(s) so that I can provide feedback to the team.

All, we don't have new details to share at the moment. As the team is working diligently to bring new features to this service offering, I would advise creating a feature request and upvoting.
