  title: Amazon Lake Formation Audit Resource Permissions
  summary: Enumerate registered data lake locations and list the permissions on a selected resource.
  description: >-
    A read-only governance audit flow. The workflow lists every resource
    registered with Lake Formation, describes the resource the auditor is
    interested in to capture its data access role, and lists the principal
    permissions on a Data Catalog resource so an access review can be performed.
    Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
