Add Buttons in Probe Basic

Hello,
i need some buttons in Probe basic which activates outputs from my Mesa 7i76e. The attached photo show what i need. 
I found /user_buttons/template_user_buttons/template_user_buttons.ui (attached). Would that a nice place add the buttons. But so far i don´t know how to start the ui ind Probe Basic GUI.

Best regards
 

You can add to the user tab and turn it on in the initial file, this is covered in the docs

Great, i´ll check tomorrow.

Hello,I've been working on this for the last few days and now understand how to add switches graphically under user_buttons/template_main/template_main.ui (see attached photo).However, I don't know how to link the light switch to the output of my Mesa 7i76e, for example. I tried to implement net light => hm2_7i76e.0.7i76e.0.0.output-02 <= qtpyvcp.light in my postgui_hal. Unfortunately, that didn't work. What am I overlooking as a newbie? 
And in addition i´d like to have a nice looking Led right to the button. Red = off, green = on. I could not find one in QT Designer. Alternatively, the button itself could change from red to green.

Translated with DeepL.com (free version)

On the probe page in qt designer, there is a button where the probe to is and the output from linuxcnc goes to the led on the probe graphic, use that as a template

You mean that led at the attached photo? I can´t find a probe section in QT Designer or do i need to be in Probe Basic Development modus instaed of stable?

And can you help me here ->
