Amazon Seller Central Keep Rejecting Developer Access

I would like to know what is the correct way to fill up the application the get access to SP-API Direct-to-Consumer Shipping. I go to the App registration and I mark all the related API access except for Tax related items and vendor. The reason is because the application is an ERP system that will download orders and fulfill in house the orders and shipped them out. The application will also provide updated to the order until it is closed. Unfortunately, amazon keep rejecting and they are not providing specific answers to fix what is wrong with the app registration.

Detail Message:

"We have completed our assessment and have determined that you do not meet the requirements for Restricted SP-API. To protect Amazon Customers, we only consider sharing Customer data (“Restricted access”) with third party Developers that offer features that are materially different from existing applications. The Developers that meet these criteria must then go through rigorous security reviews with Amazon."
