Registration page in zoom events

I've just signed up to zoom events and finding it really difficult to understand. I created an event linked to an existing webinar that is set up with registration. 

Where is the registration page set up in zoom events? I want attendees to enter their details such as name, email, company name, job title etc.  Do I need to create this in zoom events, or does it link back to the original webinar?  It doesn't seem right to have a link to a separate registration page and a link to an event page. 

What am I missing?
