Add navigation overlay buttons when in Something like Android Auto #4
Description
When you open Android Auto from the Unity app it opens up in fullscreen and there is no way to get back in the Unity without closing Android Auto by disconnecting the phone.
So there should be an always on top button in a corner that lets you go back to the Unity app/close Android Auto and also a volume slider since you can't change the volume from in Android Auto. (Maybe one button that opens a little popup with the close button and volume slider)
