Removing icon "Toggle grid view" with CSS - only works for administrator?

I am trying to remove (hide) the icon “Toggle grid view” which is located in the upper right corner of the files app.

I managed that with a simple Custom CSS code snippet:

#view-toggle {
visibility: hidden;

This actually works, but only for the administrator. All other accounts still see the icon.
When I check the active CSS code with those users, I cannot see the "visibility: hidden;

What else do I need to do that this Custom CSS code applies to all users?


Nextcloud version: 19.0.5)
Operating system and version : Ubuntu 20.04)

Got it…
Custom CSS was set to be available only for group admin… I fixed that and now the toggle is gone.
