USER section in Probe Basic

Hello, I'm a beginner in Probe Basic UI and want to add some machine specific buttons in the USER section of the UI screen.
I understand that the layout is designed by using Qt Designer but have no glue whow to link/connect the button with the hal pin or signal of the machine.
Any advise ot link to a helpful YT video is apreciated. I could not find a YT tutorial or step-by-step guide/documentation.

check the qtpyvcp tutorials for buttons, the same method is correct for setting up user buttons in the user button ui
