Synchronizer ignoring contact groups

Nextcloud version (eg, 20.0.5): 27.1.2
Operating system and version (eg, Ubuntu 20.04): Windows 11 home
Apache or nginx version (eg, Apache 2.4.25): replace me
PHP version (eg, 7.4): 8.1

The issue you are facing:
I’ve today set up Synchronizer for Outlook 365 to use my Nextcloud contact list. Contacts are there ok, but it lacks the facility, unlike Thunderbird say, to keep the contact groups I have in Nextcloud. Is there a way to bring these groups to my Outlook contact list?
