[FEATURE] Additional notification sounds

Is there an existing request for feature?

What feature would you like?

Hello! This is not the most vital feature, but it would be very convenient if you added new notification sounds, including ones exclusive to your app. So that I could select them and immediately understand when a notification arrives that someone wrote to me in Session.

Anything else?

For example, Signal has its own individual and quite pleasant sound.
