Hi there, @NikkiiOrtega317 ...
I assume that you are referring to the Guide located at How do I generate a pairing code for an observer as a student?. In this Guide, under the heading of "Pair with Observer", there is the following:
Note: If the Pair with Observer button doesn't display in your User Settings, please contact your institution for assistance with pairing with an observer.
I recommend reaching out to your school's Online Learning / eLearning / Distance Education team or your school's Canvas administrator(s) to see if someone can assist you.
I hope this will be helpful. Good luck to you!
