When preparing your app for production
The last section on the Basic information is
Deauthorization Notification
Endpoint URL
Provide the URL and the webhook events will notify the app is no longer active when a user removes your app. Learn More
However, the link for further information returns a page not found
https://developers.zoom.us/docs/build-flow-beta/prep-app-for-prod/#link--support
Can you please provide the information and hopefully a valid page link?
All the best
