Updating SHarePoint 2013 Designer Workflow Status using PowerShell

I have a SharePoint 2013 On-Premise environment where I am creating a SharePoint Designer 2013 Workflow using SHarePoint 2010 Workflow engine. I need to update the workflow status to Approve using Power Shell. There are multiple task created sequentially and each task is created based on the prior task completion.

Do anyone has any information on this?
