PubSub

inner class PubSub

Provides publish-subscribe messaging within the meeting.

Use this to send messages to specific topics and subscribe to receive messages from other participants.

Subscriptions are scoped to one joined session. Leaving the meeting or switching to another room discards every subscription and every registered PubSubMessageListener; nothing is restored automatically, so subscribe again after rejoining. Brief pubsub connection drops within a session are handled internally and do not require this.
