How to add more profiles for users before entering the meeting

Hi,
It seems that only the email and diaplay name can be configured before user entering the meeting room. But I want to add more information about participant, such as organization, region, etc. How should I do this?

I noticed that in jitsi-meet project, react/features/settings/components/web/ProfileTab.js can config the setting panel in welcome page. But I have no idea to send these new profiles to conference room. For example, the host of a conference need to confirm participants organizations and their emails, under lobby mode, how to send the organization info and display it on host’s screen as a notification?

Thanks!
