Controlling moderator allocation and bug on ios devices

Hey guys, could you help me with some of the stuff that i am having issue implementing on my jitsi server.

  1. How can i make the person who joins first as the moderator instead of the person who joins later.
  2. And if a person who joins the meeting through safari and if anybody else joins after them then the person who joined with safari is getting kicked irrespective of the order they join.

Thank you!
