At my community college, students will see Zoom in their Course Navigation Bar for the class they are enrolled in. To see this, you need to be in the Canvas course, not just on your Dashboard.
Has your semester already started? If your spring semester hasn't started yet, it's probable that your instructor hasn't published his/her Canvas course yet. That means that the course still doesn't show up on your Dashboard. Many instructors wait until the day of the course or perhaps the weekend before the semester to publish their courses.
If the semester has already started, first check your school email account for an email from your instructor. If you are still having problems, send an email to your instructor for help. You can also find your school's Canvas "help desk" on your school's website.
