  title: Microsoft Office 365 Find or Create Group
  summary: Look up a group by display name and create it only if it does not exist.
  description: >-
    An idempotent group provisioning pattern. The workflow searches existing
    groups with an OData filter on displayName, then branches: when a match is
    found it reads that group, and when no match is found it creates a new group.
    This avoids duplicate groups when a provisioning job runs more than once.
    Every step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.

  summary: Resolve a group by display name, creating it when absent.
  description: >-
    Lists groups filtered by displayName (200), and branches on whether a match
    exists: reads the matched group via GET /groups/{group-id} (200), or creates
    a new group via POST /groups (201).
