language translation

Hello, I have a workplace account. I am trying to figure out language translation. When I set the close caption to a different language, it always defer back to English. Some of my student students for example speak and read Spanish. Is there a mechanism for The user who speaks a different language to receive close caption just on their screen and their preferred language. Also, when the instructor is speaking, I understand there is a feature where the end user who speaks a different language can hear the instructor voice in their language. I find some of the land translation features to be confusing. Essentially, I’m trying to assist my students who speak Spanish to receive their closed caption in Spanish, and also have the instructor voice translated in Spanish. It is also my understanding that the Spanish translation in zoom is not very accurate.
