Newbie question - HabPanel on OH 4

I’ve seen numerous YouTube and Blog articles about HabPanel which seem perfect for my application.
My OH 4 environment is up and running fine with modifications to the Overview page.
When I try the examples for HabPanel like:
http://192.168.0.nnn:8080/habpanel/index.html#/
I get a message that this isn’t found.
Is HabPanel still supported and if so, how does one get started?

Tutorials and Solutions is a place to post a tutorial or solution, not a place to ask for one. I’ve moved this post to a more appropriate category.

Have you installed the HABPanel add-on?

Thank you.
I couldn’t figure out how to get the add-on but just found it.

Where to find HABpanel add-on?
Here I can see Basic UI only
