In my uwp app (xbox, webview2, react) I can deep link to (open) the Xbox’s Library app using the library:// Protocol URI (found here) like this:

  await Windows.System.Launcher.LaunchUriAsync(new Uri("library://"));

But I haven’t been able to work out the path to this Manage Updates screen (Library > Manage > Updates):

I’ve tried this, which according to these docs “… will launch the Library page.” BUT it only opens the store homepage.

await Windows.System.Launcher.LaunchUriAsync(new Uri("ms-windows-store://downloadsandupdates"));

I’ve also tried all of these library:// URI protocols without any luck

  await Windows.System.Launcher.LaunchUriAsync(new Uri("library://"));
  await Windows.System.Launcher.LaunchUriAsync(new Uri("library://manage"));
  await Windows.System.Launcher.LaunchUriAsync(new Uri("library://manage/updates"));
  await Windows.System.Launcher.LaunchUriAsync(new Uri("library://Manage"));
  await Windows.System.Launcher.LaunchUriAsync(new Uri("library://Manage/updates"));
  await Windows.System.Launcher.LaunchUriAsync(new Uri("library://manageupdates"));
