Is there an API Doc about the "Zoom Voice Recorder"?

Hi Zoom Team,

Hope you are doing well. I have a client who is using zoom Meetings, Zoom Phone and Voice Recorder. I’m good to figure out the APIs of meetings, Zoom Phone and the ZRA APIs. But it seems there is not a formal doc for the Voice Recorder. May you please guide me how to get the recording + transcripts for the Voice Recorder?

Or, if that goes to the Meetings API, how can I distinguish the data between Zoom Meetings and Voice Recorder?

Thank you!
