Trigger a Flow whenever a new message is added to a private Slack Channel.

Note: Pairing this event with a Send Message to Channel action may create a loop. Notifying the channel when a new message is added will cause the flow to respond to its own messages.

Unless otherwise indicated, field types are text.
