Collaboration Apps not displaying in Canvas Course

Google Docs is one example of a collaboration app available in Canvas
By default all courses have been assigned Google Docs
If the app is missing from a course it's because someone removed it, and there's away to restore it:

• Course > Settings > Navigation and then you can click and drag the Collaborations to be viewable for students

If the above step does not resolve the issue, escalate the request. A Canvas admin will need to toggle the setting

• Settings > Feature Options called “External Collaboration Tool” toggle it to OFF
