How do I enable the advanced options for an event in Zoom Events?

Hello I am creating an event on Zoom Events for the first time. In  the Event Options page, under 'Joining the event', I should be able to  see the following 3 advanced options (listed below), however the only advanced option that I can see is 'Enable Q&A'. I had a look at the settings but there was no option to enable all of the advanced setting options. Can someone tell me how I can see all the advanced options? Thank you. 

• Attendees can join event 15 minutes before the event starts: Click the Attendees can join event 15 minutes before the event starts toggle to enable or disable it. By enabling, Attendees can join the Meeting event before you start the event.
• Waiting Room: Click the Waiting Room toggle to enable or disable it. By enabling, you will need to manually admit Attendees from the Waiting Room in a Meeting event.
• Enable Q&A: For Webinar events, the question & answer (Q&A) feature for webinars allows Attendees to ask questions during the webinar, and for the Panelists, Co-hosts, and Host to answer their questions.
