Three finger gesture to window overview is not working
I couldn't find any information which gestures are supported by shell, but afaik a three finger pinch gesture should open the window overview, which doesn't work for me.
The four finger workspace swipe gesture is working fine. Other three finger gestures in other apps (for example Builder) also work fine.
Is there a gesture to open the overview?
