Game: free demo app but in-app purchase for full game?

Hi. I'm working on an iOS game port. I noticed that there are a couple of games that are free to download, offering a demo or trial, and then allow users to purchase the full game as an in-app purchase.

How does the review process for a game like this work?

Resident Evil 4 (https://apps.apple.com/us/app/resident-evil-4/id6462360082?platform=iphone) is the example I'm using. The game is free, but only a small portion of it is available. You can then purchase the full game using an in-app purchase.

Thanks for any help you can provide!

Hi. Thanks for your reply. Where exactly do I need to sign in to select the "app review appointment"?

Circling back to my question, it is not only about the review process but also the implementation part, which is not entirely clear from the documentation. Is this demo self-implemented?
