Are there any options available for streaming text to an avatar?

Hi, I am looking at the https://docs.heygen.com/reference/send-task operation in your API documentation and was wondering if there's any way to stream text to the avatar instead of sending it all at once?

For our application, we have the option of receiving a streamed response from an LLM, so would be good if, once we receive the first token back from the llm, we could then initiate the text to speech.

Thanks,

Odran
