Append audio to an existing conversation using a URL and process the content.
The URL must be public and go directly to the media that you want to submit. Redirected URLs, such as URLs shortened by platforms like YouTube and Bitly,
are not supported.
The response returns the same conversation ID that you used for the request, and a job ID. The conversation ID can be used with the Conversations API to generate conversation intelligence. The job ID can be used to check the status of the processing job.
