What modules do you want to add there?

I'm trying to populate the participants metadata in my setup (using JWT/OIDC auth), so I am following this solution that is doing the job for me https://community.jitsi.org/t/jibri-metadata-json/20254/20. I'd like to restrict this module to the guest virtual domain, though, as currently I need to add it to GLOBAL_MODULES.

That is confusing, in general you should not need any modules under guest and that post mentions guests which are moderators which is another thing that should not be possible.
So if the module is following the presence of the room participants that should be under the main muc component, as the participants in the room use the room nick as jids for updating their presence in the room.
