I am trying to implement the required Marketplace Account Deletion notifications. However, when I go to my setup (https://developer.ebay.com/my/push/?env=sandbox&index=0), I do not see an option for that. I do see radio buttons for Platform Notifications (push) and Client Alerts (poll), but not the "Marketplace Account Deletion" button to the right of that. We receive orders from MIP and push fulfillment data also through to MIP, so we want to make sure we are in compliance with any privacy requirements necessary. Can someone please help me understand why the radio button for "Marketplace Account Deletion" is missing and what I need to do to make it appear?
