Hi @PRINCE PATIDAR ,
Unfortunately, Action Center is deprecated and no longer being worked on. Therefore, Action Center has been removed in the latest versions of Microsoft Edge.
You might have read from the documentation that you could track Rewards points in Action Center. That documentation actually needs updating. If you need to track Rewards points, you can turn to Microsoft Rewards app in the sidebar. Just search for Microsoft Rewards in the sidebar, then you are good to go.
