  title: Sendbird Moderate the Author of the Latest Channel Message
  summary: Read a channel's latest message, identify its author, and mute that user.
  description: >-
    A reactive moderation flow that pulls the most recent message in a channel,
    extracts the author's user ID, and mutes that user in the same channel. It
    branches on whether the channel has any messages so an empty channel ends
    cleanly. Useful for automated abuse response triggered off the latest post.
    Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
