So recently Apple released Custom Product Pages, which works by adding the ppid parameter to the link (e.g. https://apps.apple.com/app/id0000000000?ppid=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)

But I didn't find any information on how to understand from which ppid used installed the app!

Does anybody have some experience with it? Can it be parsed from launchOptions or something?
