What is the equivalent CLI command for Visual Studio's "Publish > Create App Packages..." right-click action?

[shirakaba]

I have a Windows Application Packaging Project (myapp.Package) that wraps two apps, made by following this old official guide. It wraps:

1. a React Native Windows UWP app (myapp).
2. a Win32 app (AudioCapWinThirtyTwo).

I create release builds by right-clicking myapp.Package in Visual Studio and selecting Publish > Create App Packages..., as follows:

I would like to call this via the CLI in order to set up CI builds, but I have been unable to figure out what the corresponding CLI command would be.

For non-WAP projects, it sounds like the build command would normally be npx react-native run-windows --release. But I believe in the case of WAPs project like mine, that command would only build the UWP app. Am I mistaken?
