  title: EventBridge Scheduler Create Then Update Schedule
  summary: Create a schedule, update its expression and state, then read it back.
  description: >-
    Creates a schedule in the default group, then performs an in-place update of
    its schedule expression and state. Because UpdateSchedule overrides the
    existing schedule with every value in the request, the flow finishes by
    reading the schedule back to confirm the new configuration took effect.
    Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
