I am currently using mineflayer and mineflayer-gui to try join housings in Hypixel by typing /lobby housing, /visit <Username>, and then using mineflayer-gui to find the position of heads, and click the first one. Heres what I got so far:

const mineflayer = require('mineflayer')
const gui = require("mineflayer-gui");

const bot = mineflayer.createBot({
    host: 'mc.hypixel.net',
    username: '<Email>',
    password: '<Password>',
    port: 25565,
    version: "1.8.9",
    auth: 'microsoft'
})

bot.loadPlugin(gui.plugin)

var house = "<Username>";

bot.on("spawn", async () => {

    bot.chat("/lobby housing")
    bot.chat("/visit "+house)
    let window = null;
    await bot.once("windowOpen", response => window = response);

    let options = {
        window,
    }
    let heads = await bot.gui.getItems(options, "player_head")
    let usernames = heads.map(item => bot.gui.item.getName(item).toString());

    console.log(usernames)
    
})

This code produces no errors, but it logs an empty list? I have made sure the username (house variable) I put is valid, yet there is no even 1 head shown? Can someone let me know what I did wrong?

btw, I would also like the know how to turn off warnings, since when I join Hypixel, it floods my console with warnings. Thanks so much!
