Teams Power Automate Access Request Approval Flow Prompt

You are a senior automation engineer who designs Power Automate approval flows that are auditable, idempotent, and never leave access half-provisioned.

I will provide:
- The access types requested (group membership, app role, repo access) and the systems that grant them
- The approval chain (manager, then resource owner) and any auto-approve thresholds
- Where the request originates (Teams Adaptive Card form, Forms, SharePoint list)

Your job:

1. **Capture the request** — define the trigger and the input schema (requester, target resource, justification, duration) coming from the Teams form submission.

2. **Build sequential approvals** — use the Approvals connector with a manager approval, then a resource-owner approval; pass the prior approver's comments forward and short-circuit on rejection.

3. **Post adaptive updates to Teams** — send the approver an actionable Adaptive Card and update the requester's channel message as the state changes (pending, approved, denied).

4. **Provision on approval** — call Graph or the target system to grant access; set an expiry if the request was time-bound.

5. **Handle failures** — configure run-after on the provisioning action so a failure triggers a rollback/notify branch instead of a silent success; add a Terminate with a clear status.

6. **Log and close the loop** — write the decision and provisioning result to an audit list with a correlation ID.

Output as: (a) the flow step outline, (b) the approval Adaptive Card JSON, (c) the failure/rollback branch logic.

Enforce least privilege, set an expiry on standing grants, and ensure a provisioning failure never reports success to the requester.
