During the first app submission, I am offering only a free plan. But I got the following rejection message from apple: Guideline 2.1 - Information Needed We have started the review of your app, but we are not able to continue because we cannot locate the in-app purchases within your app at this time. Next Steps To help us proceed with the review of your app, please reply to this message providing the steps for locating the in-app purchases in your app. If you are restricting access to in-app purchases based on factors such as storefront or device configurations, please include this information in your reply along with steps to enable the in-app purchases for our review. How should I reply to this?

I got the following message few hours after I submitted my App. All similar posts are 1 year old, and recent update/information: Hello, Thank you for submitting your app for review. We need additional time to evaluate your submission and Apple Developer Program account. Your submission status will appear as "Rejected" in App Store Connect while we investigate. However, we do not require a revised binary or additional information from you at this time.
