[SOLVED] Group folders : How to remove advanced permission rules (logged as an admin)

Hi All
We are using Group folders here and I just can’t find how to remove advanced permission rules, when I am logged as an admin user. Can anyone please help me?

Nextcloud version 21.0.5
PHP version 7.4.19

Sorry i can not test it. But perhaps you can use this in opposite way.

Hi all
I am sorry.
On a bigger screen, I could see the cross next to the adavanced permission rules! I could delete the permission by clicking this cross

Thanks, devnull for your message
