Groupchats - amount and votekick

Please add the ability to vote kick someone from a group chat- or at least remove deleted users because my friends and I have a group chat that has lasted a year and one of their accounts was deleted, and now we can't do anything. Your suggestion may be to just make a new group chat but we don't want to lose everything we've had for over a year, it means a lot to us. An alternative to adding votekick could be making the group chats slightly bigger but that could result in the same problem. Thank you!
