المعاملات
appIdStringمطلوبApp ID for the UTD Stream Engine (X-App-Id).
appKeyStringمطلوبPublishable app key (no backend). The kit mints tokens directly with X-App-Key; the server secret never ships.
userIdStringمطلوبLocal user's identity.

roomIdStringمطلوبRoom / LiveKit room name to join.
roomOwnerIdStringمطلوبIdentity of the room owner (becomes host); everyone else joins as audience.
adminIdsSet<String>القيمة الافتراضية = const {}Identities the owner will promote to admin (moderators) once present in the room.
