Zoom webinar and Hubspot registration

I am organising a Zoom webinar with registration details to be passed to my organisation's Hubspot account. However, I noticed that Hubspot contacts that already exist will not be updated to reflect a new Zoom registration activity. I thought I might instead create a Hubspot form and a landing page for the webinar, with an automation for anyone who fills out the Hubspot form to be automatically registered in Zoom as well. But I can't figure out if that's possible - does anyone have any experience?

Also, is there a way to view a registration list in Zoom webinars?

Thank you!
