Why i can't use trans extension in some courses

why i can’t use trans extension in some courses . so I have difficulty reading and understanding the video

@anhnee I know at least in the lecture videos you can click on this little button (the red circle) and choose a language for subtitles (granted, even in English they are not always perfect but).

Why, is your preferred language not listed ?

*Even I use the subtitles and I am a native English speaker.

@anhnee

Perhaps you re doing short course where transcripts aren’t available.
