The approval timeline depends on the approvers in your organization.
When you submit a request, it appears in the "Open Requests" tab for approvers to review. They'll receive a notification and can then examine the details you provided. Approvers have the option to modify information if needed before making a decision.
Rest assured, once your request is approved, you'll receive a notification about the successful creation of your team. If you want to check the status, you can look under the "Open Requests" tab in the Requests section of Teams Manager.
