  title: Azure Web PubSub Join Group, Send, then Leave
  summary: Add a connection to a group, broadcast a message to that group, then remove the connection.
  description: >-
    A scoped fan-out pattern: a connection is added to a named group, a message
    is broadcast to everyone in that group, and finally the connection is removed
    from the group so it no longer receives future group traffic. Every step
    inlines its request — Authorization bearer header, required api-version query,
    request body, and documented status codes — so the flow is self-describing.
