Unable to update Agent voice with an ElevenLabs voice

I am unable to find/use any of the Elevenlabs voices with a D-id agent.

I have a custom agent that I am trying to update with the patch fetch method given by the API. I have used both the DOCS tester and html to send the fetch request, both times recieving a successful response, but the voice is not changed.

The presenter is as follows

presenter: {
      voice: {
        type: 'elevenlabs',
        model_id: 'eleven_v2_flash',
        voice_id: 'goT3UYdM9bhm0n2lmKQx'
      },
      type: 'talk',
      stitch: true
    }

The header seems correct.

I have used the following sources to attempt to fix my issue
