Hello. I have seen in various images that an entry to the web interface can be placed in the control bar (lovelace) of Home Assistant, but there is no button that automatically integrates it as occurs in other add-ons.

I have tried in several ways but I can't get it, maybe it's because of SSL.

Any help please?
I answer myself after the last fruitful test:
'# In configuration.yaml entry
