Node.js tools are unavailable on my project.

I'm developing a Angular/ASP.NET MVC based NopCommerce plugin. In order for it to load within the host, it must be built as a netcoreapp2.2 Class Library. Unfortunately, I am unable to use node.js tools for Visual Studio 2019. Right-clicking on my package.json file doesn't display the restore packages option, nor is the node_modules package folder with the node.js icon.

I checked my installed workloads and everything was properly installed. I figured I might need to install an additional component, so I searched ad encountered Node.js tools for Visual Studio (https://visualstudio.microsoft.com/vs/features/node-js/) and clicked the Download Visual Studio button which installed the release version. The web page failed to make it clear that it was already included as a workload. So I wasted more time downloading and installing something I already had. Not to disappointment, Microsoft's documentation lead me to a usual dead end.

Well, hours later, I still can't get it to work at all. I suspect it doesn't work with Library projects. Correct? If so, how do I enable it?

Start by reproducing the missing Restore Packages action and node_modules icon in Visual Studio 2019 for a netcoreapp2.2 Class Library containing package.json. Trace how Node.js Tools detects project types and determine whether this project type is supported; done means the compatibility behavior and any required setup are clearly established.
