Android MVVM - Where to bind to a Mediaplayer bound service?

I have a permanent bound service with a Mediaplayer and a MediaSession. I am refactoring my app to an MVVM architecture with HILT .

I'd like to know where I should bind to the service and where to save the IBinder and the media controler :

• The application ?
• the UI fragments or activity?
• the shared viewmodel ?
• the repository ?
• somewhere else ?

The difficulty of using the repository is that it is injected in the viewmodel from a HILT Module.

It would be much appreciated if you could provide some guidelines.
