Show group membership(s) of a device or other entity

The possibility to create group helpers is a great feature.
I can build groups of devices, for example lamps.
It would be helpful to see or search, a member of which group(s) a device or other entity is.

Meanwhile i have found a work around:
Go to “developper tools”, tab “states”
Filter the groups if possible
Search in the results for the entity name
Group members are shown in the column “attributes”.

I hope, there will be solution for easier access.
I have placed a feature request 8 months ago.

Yes, I agree. I would like a card on the device page showing the helpers that device are used in, the same way that Automations, Scenes and Scrips are shown today.
