Reading chatbox without being signed into it

I have a bit of a random question. Can anyone tell me if it's possible to make it so the chat that is happening (people talking) on a chatbox is possible to be seen by people that aren't signed into it? I remember that some time ago, that was possible and it was the default way it was. I liked the possibility, as an admin, of being able to check out and moderate the chatbox without being signed in.. I tried looking around the admin panel and searching on this forum, I still haven't found an answer... Anyone can help?

Thank you in advance

Oh. I see. Thank you.
