Hi @StephenBartoril,

For most modern third-party integrations with Canvas, you'll need to work with your school/institution Canvas team to have the app installed.  I will note that by default, the newest McGraw Hill integration uses modules instead of having a link added to the course navigation menu, so it may already be installed and you're just looking in the wrong spot.  Even McGraw Hill's own support agents seem confused by this change, which was initiated on their end...

Hope this helps!
