noticed something here, dont underasand why. but here in Retrieve the registrations for a device in Apple Developer Documentation in Retrieve the registrations for a device. There is no Authorization in the header to include, however, other endpoints support that? Is this header will be sent from Walle? meaning that it has been missed in the documentation ?
