How do I enable "search" and "reason"?

[snakeninny]

There's only message parameter in the doc:

import {ChatGPTReversed} from "chatgptreversed"; // const {ChatGPTReversed} = require("chatgptreversed");

const chatgpt = new ChatGPTReversed();

const result = await chatgpt.complete("Hello, how are you?");
console.log(result);

// Output: Hello! I'm here and ready to assist you. How can I help you today?

How do I setup the key/token, enable "search" and "reason"?
Thanks
