Switch mouse cursor automatically

Hello, I try to find a solution for a workflow that I can’t set up.

I use a Wacom pen tablet to control a 2nd monitor. Wacom has a function where the mouse cursor automatically jumps to the 2nd monitor when you use the pen (This pen behavior can be activated in the settings menu of Wacom app). I would like to use a Magic Mouse to control 1st monitor in the same way what the pen does. So when I switch from the pen to the Magic Mouse, the mouse cursor should automatically switch to the 1st monitor.

How can I program/setup this behavior for the Magic Mouse in the BTT app?

Thanks for your help!
