How to Set Language (e.g., Korean) When Creating an Agent via API?

Hello,

I am currently testing the agent creation using the following endpoint:

Create an Agent POST https://api.d-id.com/agents
While creating an agent, I would like to set the language to Korean so that the agent can respond in Korean. I noticed that the Studio interface supports language selection, including Korean, but the API documentation does not appear to include a field for specifying the language.

Could you please let me know:

Whether language selection (specifically Korean) is supported through the API?

If so, how can we configure the agent to use Korean via the API?

Thank you in advance for your support.
