Add-on: Z-Wave JS UI with Z-Wave JS (error)

I really can’t find the entities provided by this plug-in. I find nothing under development tools → states. I want to include them in Lovelace, but I can’t seem to access them in anyway, although the Z-Wave JS UI is populated by most of them.

What kind of entity IDs should I be looking for?

Did you follow the steps outlined here?
