  title: Power BI Review and Adjust Workspace Access
  summary: List a workspace's members, downgrade an over-privileged principal, remove a departed one, and confirm the final membership.
  description: >-
    The periodic access review pattern. A workspace access review produces two
    kinds of change: principals who keep access but at a lower right, and
    principals who lose access entirely. Both write operations return 200 with
    no body, so the review is only evidenced by reading the membership back
    afterwards. This workflow captures the starting membership, applies a
    downgrade and a revocation, and re-reads the membership to record the state
    the review left behind. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.

    description: >-
      Reduce the over-privileged principal to the reviewed access right. The
      call returns 200 with no body, so the change is verified by reading back.
