I dont know anything about code… Is it possible that an Apple developer implement In app purchase for me directly taking the app file From my Apple developer account ?

thanks in advance

I am afraid you will have quite the up-hill infront of you. Implementing in-app purchases require 3 things to handle them. The app itself and StoreKit API, setting up In-app purchases in Apple Connect and a separate server (Firebase or other) to handle the receipts and keeping track of who has payed for what.

Honestly, don't handle that yourself, it's too tiring if you are a solo developer and want to keep things simple and cheap. Just use RevenueCat (apparently it is forbidden to link to this website... what a joke). It's free until you reach 10k$/month and they have a great tutorial.
