Unsubscribe from Account Activity webhooks without user token



We have a number of accounts for which we had previously subscribed to Direct Message webhooks. The tokens have either been deleted from our system by the user or are no longer valid. These accounts still show up in the list of subscribed accounts via the API. Is there a way to unsubscribe from an account when you no longer have a valid user token and secret?


Can you use another user’s token (like the owner of the app’s oauth tokens) to do the unsubbing?
