title: Share a Drive document without notifying user with Google Apps Script
body: <p>I am creating a workflow process in Apps Script where a Doc is generated from a template and shared with various users for approval. The Script sends a customised email notifying a user that the document requires their approval but they also receive a second email at each stage in the process from the user whose Drive the document is stored in saying "User has shared a document with you". Is there any way of disabling these alerts? When you share a document manually from your Drive, there is a checkbox option that allows you to choose whether or not the user receives a notification. However, I cannot find a way to disable this notification with Apps Script. </p>
  
  <p>I am using <code>doc.addEditors(users)</code> to share the document. </p>
  
  <p>Many Thanks</p>
