Cannot add a circle or group as an attendee in a calendar event

Nextcloud version (eg, 20.0.5): latest
Operating system and version (eg, Ubuntu 20.04): Ubuntu 22.04
Apache or nginx version (eg, Apache 2.4.25): replace me
PHP version (eg, 7.4): replace me

The issue you are facing: I am not able to add a circle or a group as an attendee in a calendar event

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Create a circle with either individuals or other groups and circles
  2. Create a calendar event
  3. Go to attendees and try to add a circle, the search only shows individuals and does not show groups or circles

This is a major issue because without this capability, I am not able to easily invite lots of people that I have already organized into Circles to my calendar events.
