Add an icon in macos topbar

### Your use case

#### What would you like to do?

It would be very helpfull to have an icon in the macos top bar with the same behavior as linux client.
On linux (gnome), the element green icon turns on red when you receive a message and voila.

On macos, there is a permanent notification banner in the top right of the screen which appears and disappear for each messages.

#### Why would you like to do it?

It would avoid permanent banner notifications.

#### How would you like to achieve it?

### Have you considered any alternatives?

Nope.
I searched about this kind of issue here and on the web but I did not find any tips or solution.
Maybe that this subject has already been discussed and I did not saw it. If yes, dont hesitate to delete this issue (after few details if it can be done or not :))

### Additional context

Running macos 13.5.
