title: Get multiple active users in a session/Google sheets workbook
body: <p>I have managed to get Active user in the session/Google workbook using the Session.getActiveUser().getEmail(). However, is there a way to get multiple active users using the spreadsheet? For eg. 'User A' working on Sheet1 and 'User B' working on Sheet2. I would like to get email addresses of User A and User B.</p>
