Many learners install the Google Translate Chrome browser extension, so that the platform UI is presented to them in their primary language using machine translations. It's not perfect and requires manual intervention each time, but gets them most of the way there and supports 53 alternative languages out-of-the-box.
The eLearning videos probably couldn't be included in this approach.
Is it possible to implement this approach (perhaps using Google Cloud API) as an option in the "My Profile" area?
