Can't get bubblecard popup visible

Hello
recently I had a crash of my homeassistant green which somehow repaired it over night with a bit of support from my side.

Now I want to create a new dashboard using BubbleCard. Unfortunately the popup does not show up. I tried many approaches but without success, I also checked the installation of it. Everything seems to be fine.

Please can anyone send me a simple working piece of yaml on the dashboard raw editor level which I can use to see if my OS is still not ok or if my bubblecard approaches were simply wrong.
Many thanks in advance.

The very next thread has some code. Obviously with issues, but that is what any AI LLM is going to use for up-to-date input to feed back to you.

The HomeAssistant dashboard documentation may be of some use to you.

Hi!

Basicly where i think it is going wrong for you is that a bubblecard in Pop-up setup is hidden per default. in the pop-up card you make a Hashtag reference to that pop-up card you can use to navigate a normal button to that pop-up card.

Hope that helps!
