Extended card for covers

Hello,

I am looking for a cover card with extended information. Alternatively, I am looking for a tutorial/example to create my own cards.
My covers are integrated into HASS via KNX. I would like to switch the automatic shading. The shutter symbol should show e.g. mdi:window-shutter-auto when shading is activated. In addition, I would like to see if a lock/alert is active, if so show the symbol mdi:window-shutter-alert and the current alert text.

Greetings
