Lib Jitsi Meet one to one chat

I am using openfire instead of jitsi meet. when someone is connected to a room that the user does not show as online. (i thing user not send online presence). I want to implement one to one chat using libjitsimeet. how can I do it?

Clients are using standard xmpp to join muc which is by sending a presence to the room.

Check my post Prosody, Jicofo,JVB flow diagram the last part, how you can save xmpp messages exchanged in a log file. there is a to a parameter and there are messages listeners to receive those messages.
