We have been using native courses:
and they do not have a closed caption feature
Have you tried downloading the accessible versions of the courses from this page: Bridge Off-the-Shelf Content?
To my knowledge they are already fully accessible to all types of learners that may need it.
Perfect! Thank you Ike! I did not know about the accessible version available.
Happy to help! (And also that we already had it before you asked! )
