What is the difference between Chrome App Shortcuts and Desktop Progressive Web App (PWA)?
For creating Chrome App Shortcuts after following the steps, this does indeed create a shortcut on the desktop. But it no longer uses the favicon and it opens in a regular chrome window alongside all other chrome windows. Shortcuts aren't the same as PWAs. A shortcut opens it in a Chrome window, in a new tab. A PWA opens in it's own window, as a separate app. They are more like Chrome Web Apps when they had those in the app store, except now you don't have to go to the app store to get them.
