1) The problem → I don't want to delete the group as it contains a lot of important content but also this group is no longer active

2) Why is this important → I don't want to show an inactive group to my new users

3) What's your plan B → Remove all the users from the old group & make it a private group

4) Possible solutions we could build for you → Option to achieve older inactive group so it won't be visible in the main group section but can be revisited to retrieve some important info
