Missing Sharee Groups entries in sharing search

Steps to reproduce

(I must note, that it might be difficult to reproduce, because the nextcloud instance has several thousands groups.)

1. Open the calendar edit/sharing modal
2. Enter a exact match in the SharingSearch Field
3. Check API response

Expected behavior

It would be nice to also make the exact matches available for selection (returned from /ocs/v2.php/apps/files_sharing/api/v1/sharees?format=json&search=115&perPage=200&itemType=principals).

Actual behaviour

The exact match is not available for selection.

/ocs/v2.php/apps/files_sharing/api/v1/sharees?format=json&search=102&perPage=200&itemType=principals returns in the payload under "ocs":{"data":{"exact":{"groups":[]...}}} the requested group e.g. named "123". But only the fuzzy search results are available "ocs":{"data":{"groups":[]...}}}. Fuzzy search result number may vary. Just in some but not all cases the exact match is missing.

Additional info

No response

Start at the calendar edit/sharing modal and its SharingSearch field, then trace how the /ocs/v2.php/apps/files_sharing/api/v1/sharees response is converted into selectable groups. Verify the exact group entries are included alongside fuzzy results, using the reported API response and reproduction steps to confirm the fix.
