AVM Fritz!SmartHome Integration: Provide Fritz climate groups as thermostats

The fritz smart home integration is working nicely, however I am unable to access/control the climate groups I defined in the fritzbox. The individual thermostats are available and can be controlled just fine. In my living room however I defined a climate group, which links two thermostats. I would love for this group to be available in home assistant as well. This would avoid residing to third-party addons and defining the groups multiple times.

This should already work out of the box - at least for me it works with a group of two FRITZ!DECT 301 … i’ve access to both thermostats individually (sure the FritzBox will sync them, as they are grouped) and i’ve access to the group
