How do I output the console.log result in Nodejs code to BAS variable?

This is probably a noob question but I dont know how to take what I output to via console.log in this code, to a BAS variable I can use later in BAS. Here is the code:

const OpenAI = require('openai');

const openai = new OpenAI({
  apiKey: [[CHATGPTAPIKEY]]
});

async function main() {
  const completion = await openai.chat.completions.create({
    model: [[MODEL]],
    messages: [
      {"role": "system", "content": "You are a "+[[COMMENTSTYLE]]+" assistant."},  
      {"role": "user", "content": [[SAVED_TEXT]]}
    ],
    temperature: [[TEMPERATURE2]],
    max_tokens: 150,
    stop: ["\n", "User:"],
    n: 1
  });
 
console.log(completion.choices[0]);

}

main();

It does not work if I do this:

const OpenAI = require('openai');

const openai = new OpenAI({
  apiKey: [[CHATGPTAPIKEY]]
});

async function main() {
  const completion = await openai.chat.completions.create({
    model: [[MODEL]],
    messages: [
      {"role": "system", "content": "You are a "+[[COMMENTSTYLE]]+" assistant."},  
      {"role": "user", "content": [[SAVED_TEXT]]}
    ],
    temperature: [[TEMPERATURE2]],
    max_tokens: 150,
    stop: ["\n", "User:"],
    n: 1
  });

[[OUTPUT]] = completion.choices[0];

}

main();
