    function newInflator() {
        return new pako.Inflate({to: "string", raw: false});
    };

    const nativeWebSocket = window.WebSocket;
    window.WebSocket = function(url, ...args) {
        console.log("INTERJECTED WS: " + url);

        const socket = new nativeWebSocket(url, ...args);
        if (!url.includes("gateway.discord.gg")) return socket;

        let inflator = newInflator();

        socket.addEventListener("message", (ev) => {
            inflator.push(ev.data, 2);
            console.log("EVENT", JSON.parse(inflator.result));
        });

        return socket;
    };
})();

This is currently not working. Have tried multiple ways to intercept WebSocket...

Indeed, this doesn't work anymore. I haven't poked around the code base enough to figure out how to fix it.
