How do you include custom symbol resources in a package?

I am trying to include custom symbol resources in a swift package for use in other projects. I have read the documentation here: https://developer.apple.com/documentation/xcode/bundling-resources-with-a-swift-package

However there is no example code and I have created a very simple project to try and get this working but it does not.

 .target(
     name: "TestLibrary",
     resources: [.process("Resources/Media.xcassets")]
 ),

This is in the Package.swift file and the path relative to the Package.swift file is Sources/TestLibrary/Resources/Media.xcassets.

There's a GitHub project with an example custom SF Symbol SVG (but this may not be available in the future): https://github.com/kudit/TestLibrary

Including this as a package in a blank Swift Playgrounds App project and just importing the TestLibrary and including TestImageView() in the ContentView technically works (it shows the system full star image, but none of the ways of rendering the test symbol as recommended works. It does work for a few of the options in the #Preview when viewing the project in Xcode.

Anyone have any suggestions or know how to get the resources to be accessible from outside the module? I have tried both the .copy( option as well as the .process( option and neither seem to work.

Okay, I think I figured it out.

Change the .target to be this and it seems to work by calling the bundle version of Image initializers:

.target(
    name: "TestLibrary",
    resources: [.process("Resources")]
),

// test.svg was included as a symbolset
Image("test", bundle: Bundle.module)

Note that this code only works from within the module so the specific symbol needs to be exposed in Image form rather than as a string.
