Volume controls and media buttons (stop/play/pause/next etc). Generally i have had to USB overdrive since catalina for basic functionality on even old keyboards (ie: dell multimedia keyboard) But that brings its own caveats. And doing it through a dock is problematic though (it requires a reboot to function) it works fine on a mac mini. In general ive just given up on maintaining the functionality.
