Close and finalize an Approval review
After the review is approved, the moderator closes and transitions items to their approved state. You don’t need a Peer review to finalize an Approval review.
Workflow must be enabled in Admin > Organization for the items in the review, or the option to Close and transition items won't appear when you finalize a review.

To close and finalize an Approval review:
In the review, select Manage review > Finalize approval review.
