disable Safari Media Keys

Hej,

I switched to a fresh installation of MacOS and thought it would be a good Idea to try Safari (Instead of Firefox/Chrome) again.

Joyfully listening music, I joined a Google Meet in Safari. Of cause it would be nice to stop the music when in a meeting - so I pressed Pause on my Keyboard. What stopped now was the Video in the Google Meet session, but the Music was still running.

Who thought it would be a "useful" Idea to control the focused App using MediaKeys? Or even the Browser at all?

Firefox/Chrome and derivates allow to disable the Media Key Support. Where can I disable it in Safari?
