How to get correlation ID for all recordings related to a call?

API Endpoints
/phone/recordings

Description
I need to store Zoom Phone recording information in a database and create a correlation ID used to select all recordings associated with a particular call.
What field in the response from the above endpoint is safe to use for this purpose?
For example, is it safe to use recordingscall_id?
Or are there any other endpoints that can provide the correlation ID I want to get?

Thanks in advance for your answers
