Feedback for a closed window?

[metawops]

I'd love to have a Companion button on my Stream Deck have a green background color if a window (technically a window is a cover in HA) is closed and otherwise have it a red background color.
I don't see how this is possible currently six available "Change from ..." Feedback options don't seem to fit.
Am I correct? 😳
So that's an enhancement request then. 😊

The variable $(homeassistant:entity.cover.dachfenster.value) currently reports "closed" or "open" but I can't see how to make a Companion Feedback from that ... 🤔

Use the internal: Check variable value feedback.
Set the normal button color to the most common state (if it is usually closed, make the background red)
Set the feedback to:
'Variable': $(homeassistant:entity.cover.dachfenster.value)
'Operation': =
'Value': open
'Change style properties': Background, red

Incredible!! I learned something new today, thanks to you, @istnv! 🙏
It works and I didn't know that I can make value comparisons with variable contents that way! 🎉🍾🥳💃🕺
