POST <https://api.d-id.com/talks> with a cloned voice ID

I am calling POST https://api.d-id.com/talks with a cloned voice ID. Can I do so a voice ID that I synthesized using their cloning feature? I have specified the correct parameters here:

    "provider":{
     "type":"elevenlabs",
     "voice_id":"REDACTED"
  }
},

I get a TextToSpeechProvider error, saying that the voice wasn't found. Are there presets of voices which are exposed, and only those? Is there a way to expose my voice ID so that D.ID can consume it?
