How to share a Zoom link in an ecard?

Hi, I am having trouble putting a link for a Zoom Registered Meeting into a Constant Contact ecard as a clickable link.  None of their options accept the link Zoom gives me. I found a thread in which the CC help says the solution is to contact Zoom to get an actual web based link - but that isn't possible, is it? 

Surely there must be a solution to this?
