KVM Switch for use with Mac Studio and MacBook Air

Looking for some help if anyone has experience or uses the same setup?

I have an M2 MacBook Air (work laptop) and an M1 Max Mac Studio (personal machine).

I connect these to my external monitor (BenQ PD322U) and can use these independently via the built in KVM the monitor has.

What I’m looking to do is be able to use my external webcam and USB audio interface with both machines without having to change cables at the back and just use something like a KVM switch so I can change machine over at a touch of a button.

I’ve looked at lots of KVM switches but a lot of them don’t have Mac support or either can only support Mac and Windows in unison and not two Macs to the same switch.

Any help is appreciated and it’s driving me mad.

Thank you!
