How to install MSIX application into subfolder in Start Menu

I have a WPF .NET 7 application that I am trying to install in a subfolder within the Start menu. I have found this article (https://learn.microsoft.com/en-us/windows/msix/packaging-tool/create-start-group) but it still just puts the application in the main (top) level.

Below is my manifest code. Is there something I am missing?
