On user conference join get the token payload in the JitsiParticipant object

Hi, i wanna ask is it possible if i add listener on the “conference.USER_JOIN” event, when some user joins the conference with token, the JitsiParticipant object returned in the listener to contain the payload data from the token ?
I am using “lib-jitsi-meet” in react app and the scenario is that one:
From one part of the APP, a moderator connects to the server with token and make a conference. Also we are listening on “conference.USER_JOIN”.
From another part of the APP, a user also make connection to the server with token and joins the conference.
When the second user joins, on the first part of the app (the moderator) i see the user who have joined but i need the information from the token in the returned user object.
