Little question

Uh I've been confused about this for a long time. Why is there a private and unprivate chat feature like what does it mean if you leave your chat on a bot public? Can ppl see it does the creator see it? Does it pop up on your profile I don't understand!!! Anyways

I need someone to test this with me so on the all chats button if you click the eyeball it shows ur acc since it's ur chat so that might work with other ppl too! I don't know how to make the chats unprivate tho——
