Is 'Sync Person Records' the supported trigger for OIC events?

I am implementing an event-driven integration for HCM person/assignment changes using OIC. Documentation for the "Synchronize Person Records" ESS job states it generates a `ChangedPersonDetails` business event, which is what I need.

However, this event appears to be a "hidden" or non-standard mechanism, creating significant implementation challenges:

1.  **Undocumented Event:**

 The `ChangedPersonDetails` event is mentioned ONLY in the documentation for this specific job. It does not appear in any other HCM guide, API catalog, or standard business event list.

2.  **Not Discoverable:**

 The event is NOT visible in Application Composer under the list of Business Events for any application. This is highly unusual for a standard, subscribable event.
