Get all assets from RefTab API (Format RefTab API Response) - node.js

Question

I'm trying to use RefTab's API to pull custom reports, but I'm not sure how to pull the data I want from the response.
I think it might have something to do with unzipping a gunzip?
I've tried accessing res.headers and res.body, but it's not exactly what I'm looking for.
I can't seem to find anything anywhere on RefTab specifically.
I'm not experienced in using REST APIs so I don't know if this is specific to RefTab
Any help would be greatly appreciated!

My index.js file:
const btoa = require('btoa');
const fetch = require('node-fetch');
const CryptoJS = require('crypto-js');
//CryptoJS is needed for the md5 and HmacSHA256 methods
function signRequest(request) {
const publicKey = 'PUBLIC_KEY_HERE';
const secretKey = 'SECRET_KEY_HERE';
const body = request.body;
const method = request.method;
const url = request.url;
const now = new Date().toUTCString();
let contentMD5 = '';
let contentType = '';
if (body !== undefined) {
contentMD5 = CryptoJS.md5(body).toString();
contentType = 'application/json';
}
let signatureToSign = method + '\n' +
contentMD5 + '\n' +
contentType + '\n' +
now + '\n' +
url;
signatureToSign = unescape(encodeURIComponent(signatureToSign));
const token = btoa(CryptoJS.HmacSHA256(signatureToSign, secretKey));
const signature = 'RT ' + publicKey + ':' + token;
request.headers = {};
request.headers.Authorization = signature;
request.headers['x-rt-date'] = now;
return request;
}
//expected input object
const options = {
method: 'GET',
url: 'https://www.reftab.com/api/assets'
};
fetch('https://www.reftab.com/api/assets', signRequest(options))
.then((res) => {
console.log(res);
});

I changed:
fetch('https://www.reftab.com/api/assets', signRequest(options))
.then((res) => {
console.log(res);
});
To:
fetch('https://www.reftab.com/api/assets', signRequest(options))
.then((res) => res.json())
.then(json => console.log(json))
And it worked!
