Suppressing meeting invites

I am looking to use zoom to have students register for a webinar. I will implement a registration button on my site which when the student clicks it will take them to the Zoom registration page. However, once the student registers, I don't want them to get an email sent out with the meeting invite. I want to suppress that.

I will be implement a "join meeting" button in my platform for the webinar. When the webinar goes live, the students can then click on the join meeting button to join the webinar. How can I do that?
