          'resource_id' can be either course_run_id or program_uuid.
          We check for the following criteria:
          - The `audit` query parameter.
          - The user's being routed to the course enrollment landing page.
          - The customer's catalog contains the course in question.
          - The audit track is an available mode for the course.
