What is difference between electron-platform-template and electron-platform for deep linking?

I'm having some challenges setting up deep linking so it opens the correct file upon deep linking from the browser, so I came here looking for solutions and noticed that there are two different directories with different code. The electron-platform has ElectronDeepLinking.ts while electron-platform-template does not.

Compare the electron-platform and electron-platform-template directories, beginning with ElectronDeepLinking.ts in electron-platform and the corresponding deep-linking code or absence in the template. Document the difference and clarify which directory and setup should be used for opening the correct file from a browser deep link.
