Issues Editing MSIX Package to Disable LaunchWhenReady

We’re trying  to disable the LaunchWhenReady setting in our MSIX package by following the guidance provided in Microsoft's documentation. 
https://learn.microsoft.com/en-us/windows/msix/app-installer/how-to-create-custom-app-installer-ux
We initially tried using the MSIX Packaging Tool & Advanced installer to make the necessary changes in existing MSIX package, but were unable to get it working as expected.

    I don't believe that you can remove the checkbox or affect the default setting, only change the location on the dialog.  

    ...but I understand why you want to...

     

    We also allow the use of this customization, we call "branding" in TMEditX (as we don't use the update mechanisms, but I suppose it could be added by editing the xml file after it is added).  We don't offer it in PsfTooling.
