void (async () => {
    // Getting credentials from environment var: AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
    const response = await fetch('https://httpbin.org/html');
    console.log(await response.text());

    // Passing credentials as options
    const response = await fetch('https://httpbin.org/html', {
        credentials: {
            accessKeyId: 'key',
            secretAccessKey: 'secret',
            sessionToken: 'optional token',
        }
    });
    console.log(await response.text());
})();
