How to convert msix to msi?

Hello,

I am currently working with a Windows application packaged as an .msix file, which is used for connecting to Azure Virtual Desktops (AVD). I need to convert this .msix package to an .msi package. Additionally, I am looking for a way to convert a Microsoft Store app into an .msi package.

Challenges:

Converting MSIX to MSI: I need a reliable method or tool to convert the existing .msix file to an .msi file without using Advanced Installer (didn't work).

Microsoft Store App to MSI: I also need guidance on how to package a Microsoft Store app as an .msi.

If anyone is familiar with these processes, especially in the context of the windows app (yes there is an app named "windows app"), your help would be greatly appreciated.

Thank you!
