Cancel Scheduled

Cancel a connection request (or message) that is SCHEDULED but has NOT been sent yet, so it never reaches LinkedIn. Use when the user says cancel / stop / don't send / take back for something still waiting in the queue (find it with list_scheduled). Synonyms: cancel invite, unschedule, pull back, stop sending, remove from queue. If it has already been sent, this changes nothing and says so: use withdraw_connection_request instead. If it is being sent at this moment it reports that; check list_scheduled shortly.

Args: handle: draft_ handle from list_scheduled or approve_draft.
