Is there any way to send data from aws lambda to firehose

aws gateway http for auth0 authentication

which works fine and iam getting body data in aws lambda

exports.handler = async (event) => {
    // TODO implement
    const response = {
        statusCode: 200,
        body: JSON.stringify(event.body),
    };
    return response;
};

how to pass the body to aws firehose ?
