Multiple vHosts would like to login to Meet

I setup JitsiMeet on a test system, Ubuntu and Prosody. It’s working great.
meet.mydomain.com and guest.meet.mydomain.com.

Now for phase 2, I want my users who are in multiple XMPP domains to be able to create rooms.

Notice there are two virtual hosts:
users@mydomain.com and users@anotherdomain.com

I tried adding org.jitsi.jicofo.auth.URL=XMPP:mydomain.com, and that seems to be working, but it’s only one domain. How do I specify the other domains that need authentication?
