Cypress Scripts - Cross-Domain - iFrame Does Not Load

Hope all's well. Kindly request your help with this. We are executing a Cypress script that launches URL 1 - https://domain1.com. This website has an iFrame embedded that launches another site - https://domain2.com. Problem is, site 2 does not load within the iFrame and we keep getting the message - "domain2.com took a long time to respond". However, outside of Cypress if I launch https://domain1.com, the iFrame is opened and domain2 is launched and displayed successfully.

I have reviewed several posts and have performed the following,

cypress.json "chromewebsecurity": false AND "modifyobstructivecode": false

index.js, followed by package.json

const path = require('path');
module.exports = (on, config) => {
  on('before:browser:launch', (browser = {}, args) => {
    console.log(config, browser, args);
    if (browser.name === 'chrome') {
      const ignoreXFrameHeadersExtension = path.join(__dirname, '../extensions/ignore-x-frame-headers');
      args.push(args.push(`--load-extension=${ignoreXFrameHeadersExtension}`));
      args.push("--disable-features=CrossSiteDocumentBlockingIfIsolating,CrossSiteDocumentBlockingAlways,IsolateOrigins,site-per-process");
    }
    return args;
  });
};

}

I have downloaded the .crx file for this extension and renamed it to ignore-x-frame-headers under the extensions dir.

However, every time I run the test, the page for domain2.com does not load inside the iFrame.

Can someone please explain what are the steps I'm missing/executing wrong? Really appreciate your prompt and positive response.

Thanks in advance, Karthik.
