How to add more profiles for users before entering the meeting

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?
