Describe the feature or improvement you're requesting

OpenAI's chatkit-js example (https://github.com/openai/chatkit-js) shows Python backend. While that works, having .chatkit.session.create directly in Typescript ensures we can use Next.js end-end for creating ChatKit expereinces.

Below code should work when the ChatKit is implemented to the OpenAI's Node.js package. Would kindly request the team to implement this change so we don't need to install, use and deploy Python backends.

import { NextRequest } from "next/server";
import OpenAI from "openai";

export async function POST(req: NextRequest) {
  const client = new OpenAI({
    apiKey: process.env.OPENAI_API_KEY,
  });


  const response = await client.chatkit.sessions.create({
  })

  return Response.json({ client_secret: response.client_secret });
}
```Scr
