Button multiple actions

Hello,

Im trying to make a button that goes to a other tab on the screen. But while i pressed that button i wanna run a script to start the RTSP stream.

Any idea how to make this?
Ive seen before something with a helper, when that helper is pressed run a script but cant find it anymore.

Hope anyone can help me out😅

Imho a browser_mod is needed here. Otherwise you cannot navigate to a particular tab in a script.
