Shelly Pro 4PM and OpenHab3 - Button behaviour

Hey there,

I’ve just installed my first Shelly Pro 4PM.
Since we have Gira Wall Buttons (55mm frames) NOT switches, I want to change the state of an channel instead of “light on when button is pressed”. When I stop pressing, the relay opens.

I was able to edit this behaviour in every single Shelly1…
Does anyone has an idea? Kind regards and thanky you a lot!
