Cubase 15 + Status LEDs

I am new here and have no experience with programming. Unfortunately, the Grid Editor is not self-explanatory for inexperienced users like me. I also have the impression that many functions are no longer available in the current version of the editor.

But I think the possibilities are really great and would like to learn.
Are there any good tutorials for the current Grid version 1.6 ?

My specific problem is this: I have a TEK2 and Cubase 15. I have configured the buttons for transport control. Now I would like to configure the LEDs on the buttons to indicate the start/stop status of Cubase. How can I do this as easily as possible?
