I have created a '5 day course reminder - Voluntary Assignments' alert but not too sure if its configured correctly as Voluntary assignments don't have a due date, therefore not too sure on how the alert will fire for the learners that I added to the course [Voluntary Assignment].

Please advise on any help to do this, thanks.
