"Unghost" ghost chats (make it a regular chat with history)

So I really like to use ghost chats because they vanish as soon as I leave them or close Lumo (that's often what I want). But sometimes I start a conversation and realize that I would like to have it in my history.

Is there an option to do that? If not: Please allow for it (if possible with current pricay architecture)! 🙏
