One more thing left, for desktop version anyway: they need to be reorderable by dragging. And then the mobile template. And then it's done as far as the UI goes.

Still not sure how to represent these group admins in #ActivityPub objects tho. PeerTube uses a similar construct for its channels and uses `attributedTo` to link a channel with its managing user. But I can have multiple admins per group, that's the point 🤔
