`text_to_speech.convert` of `AsyncElevenLabs` returns unexpected type which cannot be awaited

[legit-programmer]

To reproduce:

client = AsyncElevenLabs(
  api_key=os.getenv("ELEVENLABS_API_KEY"),
)


async def main() -> None:
    await client.text_to_speech.convert(
        voice_id="rAsfH6d68tmh0XRGXp4D",
        output_format="mp3_44100_128",
        text="The first move is what sets everything in motion.",
        model_id="eleven_multilingual_v2",
    )


asyncio.run(main())

Error on console:
TypeError: object async_generator can't be used in 'await' expression
