iOS how to check whether the entry point is from shortcut or not

I am creating a website promoting players to add that in the shortcut. (in Safari, add to shortcut). But next time when player tap into the website from shortCut, I want to show different content. I noticed the term Web App in Apple's doc https://developer.apple.com/library/content/documentation/AppleApplications/Reference/SafariWebContent/ConfiguringWebApplications/ConfiguringWebApplications.html.

Want to ask is there a way to tell whether player comes to that page from Safari or from the shortCut?
