As much as they try to hide the fact, it is actually possible to join a Zoom meeting in your browser. That way you don't have to install a sketchy app with root privileges and directory traversal bugs.
I'm currently working without this by using a device issued by my employer, where the Zoom app is pre-installed by the IT dept. and therefore using it for the language class does not make things worse.
1. The "Join from Your Browser" links take you to the worse version, which I assume is legacy or something.
2. There is also a progressive web app version [1] that has more feature parity to the desktop app. It has the grid view built-in, but for whatever reason it doesn't seem to show as many people at a time vs the desktop app grid view.
