Widget Button for Disabling Collision

Hello,

Is there a way I could disable an actors collision with a press of a widget button?
There are two (BIG and see through/invisible) buttons that split the screen of the smartphone. The upper one would make you jump and the lower one would disable collision of the floor/platform you are standing on. But how exactly should I set up that lower button? Does anyone know any good tutorials on disabling collision optionally?
this is exactly what I’m looking to create but no instructions in the video.
Any help is appreciated!

Greetings,
