My mouse Mx Master 3 is already in bluetooth, connected and working.

This app is not showing it anywhere. If I attempt to "add device" I end up on the system bluetooth page with the mouse connected...

The only reason why I installed this BETA was because when I log in to my Mac it often stops supporting LogiOptions. It's like the personalization settings are gone, scroll wheel goes the wrong way, back button integration is broken... and now I can't get even that with this BETA app...
