How to properly upgrade windows 11 Home single language edition to windows 11 pro and activate it?

I have bought a Laptop with pre-installed windows 11 Home single language (digital license) edition (activated).

I want to upgrade it into windows 11 pro then I buy from Microsoft Partners Authorized, and I got win 11 pro product key.

I change product key using it, then it tell me that windows need to be restarted to upgrade to windows 11 pro. After restart, status of windows is Windows 11 Pro, but not activated.

Please help.
