  title: Microsoft Teams Review Channel Conversation
  summary: List a team's channels and read the recent messages in a chosen channel.
  description: >-
    Reviewing a conversation requires resolving the channel first and then
    reading its messages. This workflow lists the channels in a team, branches on
    whether any channel exists, and reads the most recent messages from the
    chosen channel. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
