Auto-Entities + Card-Mod: Hide entity state

Good day,

I use auto-entities to show me a list of the latest activity (last 5 mins) in my house for the domains motion, door and image (frigate person detection).

It works well so far but to save some screen space, I would like to hide the entity state (e.g. “open”, “detected”, “clear”, or dates in case of images).

But I am struggling to find the right card_mod style to hide the entity states. The code below does not work.

I would appreciate any help to find the right code snippet to hide the state column, thanks.
