displayName undefined using lib-jitsi-meet with JWT

Hey guys,

I’m implementing my own jitsi meet client right now using lib-jitsi-meet with JWT.
The token verification and audio is working fine but I can’t get the displayName because it’s undefined.

To get the displayName I’m trying to use the USER_JOINED event but in the callback displayName is undefined. I’m hoping that somebody is able to help.
