when added a new empty group in the hue app the group is not displayed.
this is because grouped_light is missing

Thanks for the detailed report!

This is actually a mix between a bug and a missing feature.

Since bifrost maps backend (zigbee2mqtt) groups to rooms, creating a room in the frontend, should cause a group to be created in the backend.

But this is currently not implemented, so creating the room just makes a half-empty stub.

Depending on how difficult it is to create new groups, it's either going to be that, or at least making the create operation fail properly, so the user is not promised something we can't deliver 👍
