We are replacing our Zoom JWT app with an Zoom OAuth app. To verify the webhooks we will need to use our own Custom header instead of Zoom’s header. The website page (https://developers.zoom.us/docs/api/rest/webhook-reference/#custom-header) states, " Contact Developer Support to enable this feature."
How do we enable this feature so that the “Authentication Header Option (Optional)” area is visible on the Features section of the Zoom OAuth app so we can select “Custom Header”?
