  title: Unity Lobby Join By Code
  summary: Join a private lobby by code, set the joining player's data, then heartbeat to stay active.
  description: >-
    The joining-player side of a private Unity Lobby. The workflow joins a
    private lobby using a shared join code, updates the joining player's custom
    data within the lobby (for example readiness or character selection), and
    sends a heartbeat to keep the membership active. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
