New Message in Private Channel

If you pair this Event card with a Send Message to Channel action card, you may create a loop. When a channel is notified that a new message is posted, the flow will respond to its own messages.

If a failure occurs and no channels are listed in the dropdown, then only the Enter Channel ID option will be displayed.
