Zoom Event Survey

I recently created an event (one-time Zoom event, not a webinar or meeting) for a large investor meeting and after I set it all up and we sent out the invites, my boss told me that we need to add a survey to it. I cannot find anywhere to add a survey. I talked to Zoom chat support and they said I need to set up a conference event to use a survey (and then the chat box stopped working and I wasn't able to type and continue the conversation unfortunately). Is that true or can I add a survey to an event after I have created it? Or are there any workarounds?
