By default, the events you create will not show in the organizer page, you have to change the visibility settings. It's built this way so you don't accidentally show your test events in the organizer page.

If you're in the event's admin console, click Manage Organization at the bottom of the left-side navigation to get to your Organizer Portal.

Search for the event in the events tab and click the 3 dot menu at the far right. Then, turn on the toggle to show it or turn it off to hide it. Then, click Save.
