Nextcloud office - Dark Mode/Theme

My question is quite obvious.
Is there a dark mode in nextcloud office?
I have the dark mode enabled in the appearance settings but my documents are still white as the sun.
I spend around 2h of searching for the dark mode but I can not find anything. No post that says there is or there is not dark theme.
At the moment I just feel stupid…
I hope anything can anwser me if there is one or at least planned or anything like this…

I would also like to know the answer to this. My guess is no, since it’s not controlled by the overall Nextcloud theme, but hopefully some smart person chimes in with “yeah, totally!”
