Light-popup-card through Lovelace UI edit

Hey,
I’m trying to add this popup card to Lovelace but I didn’t succeed.
The installation guide still refers to the old method of adding resources to lovelace-ui.yaml.
I don’t work with such a file (Should I?) Instead I’m using the Configure RAW UI button.

I tried to add a custom card configuration with
type: custom:light-popup-card
But it doesn’t work well.

Add the resource in Configuration -> Lovelace Dashboards -> Resources

The resources were added automatically after I installed the Plug in via HACS.

Hi Did you get this sorted? I am having the same exact issue.
