Add an Approver
For approval workflows, you only need to submit an item for approval or assign an approver if the MSP Review and Modify Approvals setting on the workflow is set to 'Always' or 'Only When There Are No Automatic Approvers'. If this action is set to 'Never', or if there is an approver automatically assigned, no action is needed.
Adding an approver can override an existing workflow (if used). Reference your client organization's configuration before assigning an approver.
