Popup "Check security warnings of your server" cannot be discarded

Describe the bug After upgrade to Collabora CODE 24.04.4.1.1, a popup appears repeatedly while editing a document with the message "Check security warnings of your server" (screenshot 1). Opening the details, there are two possible outcomes: either there are no issues found but a notice "The is_admin user property is set" (screenshot 2) or an actual error "The is_admin user property is not set" (screenshot 3). See also this post in the Nextcloud help forum.

To Reproduce Steps to reproduce the behavior:

Check that Collabora CODE 24.0.4.4.1.1 is installed.
Open a text document using Collabora.
Start editing and wait for the popup to appear.

Expected behavior No popups or at least no recurrence after checking their contents.
