Package to Microsoft Store

I wanna Package our project to Microsoft Store.
I package my project successful with UE4. And when i upload the project to Microsoft Store ,it prompt that my package type must be “.msix、.msixupload、.msixbundle、.appx、.appxupload,or appxbundle”.
So how to turn my package into these types? Please give us some advice, many thanks~
