how to stay signed in gmail using puppeteer(node js )

so what i want to do is to open an already signed in gmail account, i used this answer here by wolfy but the thing is that it would sign you out of the account after a while or when i open multiple instances with the same cookies and u have to enter the password again

here how i did it

const getCookies = async (page) => {
    // Get all cookies
    const cookiesArray = await page._client.send('Network.getAllCookies');

    // Get cookies from array
    const cookies = await cookiesArray.cookies;

    // Save cookies to file
    fs.writeFile('./cookies.json', JSON.stringify(cookies, null, 4), (err) => {
        if (err) console.log(err);
        return;
    });
}

const setCookies = async (page) => {
    // Get cookies from file
    let cookies = JSON.parse(fs.readFileSync('./cookies.json'));

    // Set page cookies
    await page.setCookie(...cookies);
    return
}

how i sent cookies

// Create page once browser loads
let [page] = await browser.pages();

// Turn on page request interception
await page.setRequestInterception(true);

// Add event listener on request
page.on('request', async (req) => {

    // If the request url is what I want, start my function
    if (req.url() === 'https://youtube.com/?authuser=0') {
        await getCookies(page);
        await browser.close();
    }

    // If the url is not, continue normal functionality of the page
    req.continue();
});

// Then go to my url once all the listeners are setup
await page.goto('https://accounts.google.com/AccountChooser?service=wise&continue=https://youtube.com')
