I need help please, harmony hub activity in habpanel

I installed the harmony hub binding everything works fine
The problem is here:
How do I add an option that I can only turn off and run a particular activity through habpanel?

What have you tried?

Please note rules 1, 4, 9, 10, 13.

I have not tried anything yet
And I was looking for answers here but could not figure anything out
I would be happy if you give me an easy guide for beginners

Unfortunately, I use the Basic UI, not HABPanel

The online documentation is sometimes a good start.
