I saw following lines when reading https://jitsi.org/Projects/JitsiVideobridge
"In order to organize a Jitsi Videobridge conference, you should open the “Tools” menu of the main window and select “Create a video bridge…”. If the option is grey and inactive, then your XMPP server does not currently have a Jitsi Videobridge connected to it. Setting up Jitsi Videobridge is very easy though, if you don’t have it in your network chances are that you can easily persuade your service administrators to include it (this page contains instructions on doing so)."
It's clear that there is no such GUI interface for jitsi-videobridge, may I guess this GUI belongs to openfire or other XMPP server?
