I am a librarian and would like to interact with other librarians or people interested in books. Lately I added a chat room (text chat) that let me add YouTube videos and images. This made users stay longer.

The issue is that I cannot integrate my user base (I have around 1500 users) to the chat room and all need to re-login.

I have checked both RumbleTalk chat and c-box chat but then the lack of 3rd party users integration is a problem, any recommendation?
