Should we add a test to check to see if the events were properly pushed? And to make sure we're not doing it for people not in the experiment?

the event has a test in the hooks file located here: https://github.com/openedx/frontend-app-learner-portal-enterprise/blob/master/src/components/course/data/tests/hooks.test.jsx#L476

and the rest of the tests are in the frontend-enterprise file here: https://github.com/openedx/frontend-enterprise/pull/373/files#diff-a7b68afa7b3c0021be0ca7641ecc0f25aeea26e6185bdaba70877d1075772efe
