I think no compliable here, since i tried it.
Even you change to App.Window.AppWindow.Id will not be working in runtime, since i tried it.

I can put my version in your PR here.
Basically, beside using our picker, I also get rid of StorageFile in below usage.

Sorry, @DinahK-2SO, I found that I cannot apply the file pickers here.
Since 1.8 stable build doesn't have all API need for previous 1.8 experiemental release for this AI project.
And our picker in 1.8 exp4 doesn't work here as well because of localization problem.
