jitsi-meet: Unable to have only one moderator when using external API ?

Hello,

I am developping a platform where Alzheimer patients can meet and discuss, under the supervision of a “moderator”. To that end, I’m trying to embed Jitsi Meet with the external API provided (see https://github.com/jitsi/jitsi-meet/blob/master/doc/api.md). However, I can’t figure out how to not grant “moderator” rights to a specific user. Every user is automatically moderator, no matter when he joins the room. Is there another command that the following one : var api = new JitsiMeetExternalAPI(domain, room, width, height, htmlElement); allowing the user to join (and not “create”/be moderator) a certain conference ?

Thank you
