My settings are lost because I'm using school zoom / Where can I shut off my classmates join sounds?

I already have a zoom account but I am using my teacher's link to sign into his class. It joins with my name and my original zoom account photo but it isn't using my original zoom account name and there are sounds for every time a classmate joins or leaves our class that I cannot turn off and it is driving me nuts. Where do you think these settings can be? I tried to access my zoom account through my school link and it made me create a new account with my student email that has nothing to do with the account I am currently using. Thank you.
