Disable User Role Using External API

I am using Jitsi external api, using my own domain (where the project is deployed) as the domain parameter.
The first 1 who joins the meeting is treated as Moderator, just want to know, how to disable that feature.

Your options are have one moderator or have everyone be a moderator.

If you implement a secure domain you can make people who sign in the moderators and every one else a giyes.

@corby, thanks for your reply.
Is there any possibily to grant all users same role through external api without doing any manual changes in mod_muc_allowners.lua
