You don't. It is absolutely infruitating. The support on the website is useless, poorly written and doesn't address many of the quirks within Zoom Events. It also doesn't address many of the thing you can't do that are common in other common event systems.
When you use the general chat, you end up talking to reps that are uninformed and try to send you regular Zoom information, that doesn't apply. Like you can't pre-assign webinars. To add a session you must press enter after adding a track, little things like that.
