  title: Amazon Data Exchange Delete Draft Revision
  summary: Find a revision, confirm it is not finalized, and delete it as a draft.
  description: >-
    A cleanup flow for AWS Data Exchange. A revision can only be deleted if it
    has not been finalized, so the workflow lists a data set's revisions, reads
    the first revision's details, and branches: when the revision is not
    finalized it deletes it, otherwise it ends without action. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
