Whatsapp Web - how to access data now?

It used to be possible to access http://web.whatsapp.com/ with the Store object in JavaScript. A few hours ago, this stopped working. How does it update chat data now? It must save the data somewhere.

I'm using this to get the Store again:

setTimeout(function() {
// Returns promise that resolves to all installed modules
function getAllModules() {
    return new Promise((resolve) => {
        const id = _.uniqueId("fakeModule_");
        window["webpackJsonp"](
            [],
            {
                [id]: function(module, exports, __webpack_require__) {
                    resolve(__webpack_require__.c);
                }
            },
            [id]
        );
    });
}

var modules = getAllModules()._value;

//  Automatically locate modules
for (var key in modules) {
 if (modules[key].exports) {
        if (modules[key].exports.default) {
            if (modules[key].exports.default.Wap) {
                store_id = modules[key].id.replace(/"/g, '"');
            }
        }
    }
 }

}, 5000);

function _requireById(id) {
return webpackJsonp([], null, [id]);
}
// Module IDs
var store_id = 0;
var Store = {};

function init() {
 Store = _requireById(store_id).default;
 console.log("Store is ready" + Store);
}

setTimeout(function() {
 init();
}, 7000);

Just copy&paste on the console and wait for the message "Store is ready". Enjoy!
