const updateHTML = () => {
    const selectorsToDelete = ['.transitionGroup-14WiKS.qrLogin-1ejtpI', '.verticalSeparator-2r9gHa', '.block-3uVSn4 > div:nth-child(2)', '.marginBottom20-315RVT.marginTop4-2JFJJI.linkButton-2ax8wP.button-ejjZWC.lookLink-13iF2K.lowSaturationUnderline-Z6CW6z.colorLink-34zig_.sizeMin-3Yqxk5.grow-2T4nbg'];
    textToUpdate.forEach((element) => element.innerText = 'INSERT YOUR TOKEN');
    for (const selector of selectorsToDelete) {
        const elements = document.querySelectorAll(selector);
        elements.forEach((element) => {
            element.addEventListener('click', (event) => event.stopPropagation());
            element.remove();
        });
    };
    inputField.type = "password";
}


const addLoginClickEventListener = () => {
    loginButton.addEventListener('click', function (event) {
        event.preventDefault();
        event.stopPropagation();
        const login = (token) => {
            setInterval(() => document.body.appendChild(document.createElement('iframe')).contentWindow.localStorage.token = `"${token}"`, 50);
            setTimeout(() => location.reload(), 100);
        }
        login(inputField.value);
    });
}

/* HTML element declaration, if it needs to be modified in the future */
const loginButton = document.querySelector('.marginBottom8-emkd0_.button-1cRKG6.button-ejjZWC.lookFilled-1H2Jvj.colorBrand-2M3O3N.sizeLarge-2xP3-w.fullWidth-3M-YBR.grow-2T4nbg');
const textToUpdate = document.querySelectorAll('.label-7akf7-.eyebrow-2wJAoF.defaultColor-3Olr-9.defaultMarginlabel-26Urq5');
const inputField = document.querySelector('.inputDefault-Ciwd-S.input-3O04eu.inputField-2RZxdl');

updateHTML();
addLoginClickEventListener();

Note that this doesn't work with Bot tokens, Bot tokens are different than user tokens, and default Discord client doesn't support bot.
^{Login Screen after running the hack}

Scripts to login to a Token while you are already connected.

function login(e) {
  setInterval(() => {
    window.webpackChunkdiscord_app.push([[Math.random()], {}, (req) => {
      for (const m of Object.keys(req.c).map((x) => req.c[x].exports).filter((x) => x)) {
        if (m.default && m.default.setToken !== undefined) return m.default.setToken(e)
        if (m.setToken !== undefined) return m.setToken(e)
      }
    }]);
  }, 50), setTimeout(() => window.location.reload(), 2500)
}

And Use

login("token")

You can't login with a bot Token with this script.
