How to set video aspect ratio to 16:9 using D-ID Talks API?

Hi D-ID community,
I'm currently using the D-ID Talks API to generate avatar videos with Korean TTS voices. My current configuration works well, but I need to create videos with a 16:9 aspect ratio for better compatibility with various platforms. The default ratio was 1:1, so I want to know is there any parameter for change the ratio.
