When I embed zoom on my website do clients still need to have the Zoom App installed?

I want to be able to embed Zoom on my Joomla website. I’m trying to avoid paying for an extension which are expensive for my volunteer work as a First Responder website. I can currently put a Zoom Meeting Link on a webpage and have folks click on the link. This works fine, but wondering what advatages there might be if I embed Zoon as an iframe or how to do this and if it’s worth the trouble.
