@alya I have updated the PR and screenshots. Please have a look.

> Thanks! The banners look fine, but they don't live-update if I change the permission settings. I think you must have tried changing permissions of user-groups because on changing permissions...

I have opened #24562 addressing the changes to be done in #24198. I have to open a new PR since I cannot do changes in existing PR.

As #24562 is merged now, I think we should mark it for integration review.

I have done the changes and updated the screenshots.

@alya please review this PR.

@alya I have added screenshots with tooltips. Please have a look.
