Redirect or copy Lambda out to S3 bucket

I have a NodeJS script that works fine and outputs to Lambda console. How do I direct the Lambda console output to a S3 bucket.

Below is the NodeJS code:

exports.handler = async (event) => {
    console.log("Start")
    let res = await sign(header, payload, keyId)
    console.log(`JWT token:\n [${res}]`)
}
