I use this online chat product for the first time today, and it feels very interesting. But how can I follow my chatting friends?

I met a stranger who plays the guitar today. She is very friendly and plays the guitar professionally, but I can’t get in touch after I disconnected.

By the way, that person is the moderator of our chat room.

Is there any way I can log in again to enter the room we chatted with before?

Thank you
