4 fingers double tap doesn't work through Universal Control

Hi here,

I'm using two MacBook Pro, let's call them A and B.

The wireless keyboard and trackpad are paired with A, and I use B via UC.

When double tapping on the wireless trackpad, the shortcut (enter full screen) doesn't work while on B. I have to use the B's embedded trackpad.

unfortunately currently Apple doesn't offer any APIs that work through universal control to third party developers (as far as I know)
