There seems to be a consensus that this is impossible. There’s nothing about this on the entire internet. I could not believe it when I saw it, but it’s plain as day. When I asked Apple support for clarification, even the rep was under the impression that Apple would never allow this, until I sent a screenshot. I still cannot believe I’m the one pointing this out. WTF?

“Browsing history Information about the content you have viewed that is not part of the app, such as websites“
This is in hundreds of iOS apps, such as PayPal. Welcome to the future, I guess.
Edit: Apple Support was unable to get to the bottom of this so I appreciate any info
Edit: Apologies for the dramatic title, I should have made this an ask.
Either way, Apple really should have thought this through more when writing the description.
