How to generate developer token for api.ent.apple.com?

We are an MDM and are trying to migrate to the new App and Book Management APIs. In this doc mentioned below it asking us to send the public key generated to my Apple contact in a plain-text file. https://developer.apple.com/documentation/devicemanagement/app_and_book_management/apps_and_books_for_organizations/generating_developer_tokens?language=objc

I'm not sure who my Apple contact is? I already understand how to generate JWT token for the api.ent.apple.com. I would like to know who can authorize the public key for the organization.

Thank you

Please reach out to apple-it@apple.com.
