How to setup voice settings from API

Hello!

How can I set voice parameters when generating avatar video via API when generating https://api.heygen.com/v2/video/generate?

I do it manually via web in the voice settings in the script I set the parameters stability 1.0, similarity 1.0, style 0, use_speaker_boost False. All fine. But how to specify the same parameters via API when generating https://api.heygen.com/v2/video/generate ?
