Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello Mitali Sharma, Thanks for using Microsoft products and posting in the community. I wish I could take care of your question, however, it would be more appropriate to post it in the Microsoft Authenticator section of Microsoft Learn (English only) as more users post these questions there, and you can click "Ask a question" where there are experts who can provide a more professional solution.
Here is the link to the Microsoft Authenticator section:Microsoft Authenticator - Microsoft Q&A
We wish you the best of luck in resolving your issue.
