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.

https://github.com/jitsi/lib-jitsi-meet/blob/2d06c3e2444d92a5fb4e73bba4718ce4febced30/JitsiConference.js#L2393 there is a to a parameter and there are messages listeners to receive those messages.
