How to add celebration emojis when students turn in the last assignment in the term.
Unfortunately there is no way to add this feature to specific assignments. If your school has turned it on it's on for every assignment in every class. It occurs automatically when a student turns something in before the due date. I don't know of any way for you to determine if it's turned on at your school other than asking your Canvas Admins, or to submit an Assignment on time while in Student View.
