  title: Knock Trigger Workflow and Inspect Message Content
  summary: Trigger a workflow then locate the generated message and read its rendered content.
  description: >-
    After a workflow fires, this flow finds the resulting message for the
    recipient, retrieves the message resource to read its delivery status, and
    then fetches the fully rendered message content for the channel it was sent
    through. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
