This year during WWDC in “ What’s New in Managing Apple Devices“ session , there was a mention “We now support token-based authentication for APNS,Now this is not new” . These are clear documentation on how token-based authentication in APNS works in workflow of remote notification third party apps (https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/establishing_a_token-based_connection_to_apns) . However I couldn’t find any supporting documentation, mentioning about how it works in MDM APNS process . Any help from this community would be helpful.
