cloudflare checkbox disappear when I comment some flag

[tzbo]

To Reproduce

const fingerprintGenerator = new FingerprintGenerator();
const fingerprintWithHeaders = fingerprintGenerator.getFingerprint({
    locales: ['en', 'en-US'],
    devices: ['desktop'],
    browsers: [
        { name: 'chrome', minVersion: 98, maxVersion: 105 },
        { name: 'firefox', minVersion: 98, maxVersion: 105 }
    ],
    operatingSystems: ['windows'],
    screen: {
        minWidth: 800,
        maxWidth: 1920,
        minHeight: 600,
        maxHeight: 1200,
    },
});
const pptr = await puppeteer.launch({
    headless: false,
    ignoreDefaultArgs: [
        "--enable-automation",
    ],
    args: [
        "--lang=en-US,en",
        "--proxy-server=http://localhost:7890",
        "--disable-infobars",
        "--start-maximized",
        "--disable-blink-features=AutomationControlled",
        // "--disable-site-isolation-trials",
        // "--disable-features=IsolateOrigins,site-per-process,SitePerProcess",
    ],
    executablePath: executablePath()
});
const page = await pptr.newPage();
const fingerprintInjector = new FingerprintInjector();
fingerprintInjector.attachFingerprintToPuppeteer(page, fingerprintWithHeaders);
await page.goto('https://nowsecure.nl/');

When I uncomment this two flags, the checkbox appears again.

"--disable-site-isolation-trials",
"--disable-features=IsolateOrigins,site-per-process,SitePerProcess",

The site adds a frame in page. As following:

<iframe allow="cross-origin-isolated">

I think it's may this problem. But I don't know how to fix it. Are there any suggestions?

If I want to inject my own codes, how should I do?
