Add more Youtube tools, like captions/lanuguage, adjust speed, go back arrow to cover some key segment again; toggle auto start

As a teacher concerned with ELA in a Title I high school, I need to have more control for YouTube videos in Manycam. Set captions/lanuguage, adjust speed, go back arrow to cover some key segment again; toggle auto start. Where are the YT video tools as I don’t see them in full screen broadcast in Google Meet.
