We are configuring a reconciliation workflow involving a Preparer, Reviewer Level 1, and Reviewer Level 2. They want to ensure that a specific user group (Viewer group) can only view specific reconciliations that have been approved by both reviewers and have a status of Closed. we need guidance on how to set permissions or filters to restrict the Viewer group's access accordingly.
