❔ Are there any guides on using Source Link with VS Code?

I am trying to consume several NuGet packages and would like to be able to step into the code to debug them. According to various GitHub issues and readmes, Source Link is supported by the C# extension for VS Code(i.e.: https://github.com/dotnet/designs/blob/main/accepted/2020/diagnostics/source-link.md), but I cannot find any documentation on how to set it up anywhere.
