I have received this review from Apple, how can I try the in-app purchase as the message says?
As previously communicated, you must submit your in-app purchases products and upload a new binary in App Store Connect. Learn more about how to offer in-app purchases in App Store Connect Developer Help.
Once you've submitted your in-app purchases and uploaded a new binary, we can proceed with your review.
