  summary: List a project's access requests and approve the first pending requester.
  description: >-
    A membership onboarding flow. The workflow lists the pending access requests
    for a project, picks the first requester, and approves them at the supplied
    access level so they become a project member. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
