  title: Azure Container Apps Activate Latest Revision
  summary: Find the most recent revision of an app, inspect it, and activate it if it is inactive.
  description: >-
    In multiple-revision mode a revision can be deactivated to remove it from
    service. This workflow lists an app's revisions, reads the chosen revision
    to inspect its active flag, and branches: when the revision is inactive it
    activates it, and when it is already active it ends without a redundant call.
    Every step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
