Subscribing to Events

Use wildcard patterns to subscribe to event groups:

# All channel events
await client.subscribe("channel.*", handler)
 
# All message events across channels
await client.subscribe("channel.message.*", handler)
 
# Specific event
await client.subscribe("agent.joined", handler)
 
# Everything
await client.subscribe("*", handler)
