RealtimeTranscriptionSessionCreateResponse

A new Realtime transcription session configuration.

When a session is created on the server via REST API, the session object
also contains an ephemeral key. Default TTL for keys is one minute. This
property is not present when a session is updated via the WebSocket API.
