Hello,
Welcome to Microsoft Q&A!
Based on the document: Introducing the new Microsoft Store on Windows, it says that The new Microsoft Store on Windows supports Windows 11 alongside Windows 10, reaching more Windows customers. So you should be able to see your app in the new Microsoft Store in Windows 10. And you will get the same behavior in the Microsoft Store in both Windows 10 and Windows 11.
Thank you.
