Allow the audio/music controller to manage input between private and normal windows

I’m specifically referring to this

being allowed to manage inputs from private windows, and vice versa.
Why should this be considered? Well it would just be more convinient if you’re recieving different audio/video input from different type of cookie sessions. I don’t know if this is a security risk since I don’t know much about malware on webpages, however I don’t really care. If there is a security risk the user could be made aware.

I also would like this audio manager to detect input from google meets.
