Adding webhooks to an existing app

Description

We would like to start using webhooks to add features to our zoom app (the event created/updated/delete events). My initial testing shows that we don’t receive notifications for existing users until they reinstall the zoom app despite no change in scopes.

Is this the expected behavior? Is there an easy way to have webhooks turned on for existing users?
