Puppeteer emulate mobile

I need access an site that block request if you is navigating with desktop browser
Generating user-agent compatible with mobile is not sufficient, the only way to can view website is in inspect mode and set mobile device

How to do it in OB2?

const devices = require('puppeteer/DeviceDescriptors');
const iPhonex = devices['iPhone X'];

puppeteer.launch({headless:false}).then(async browser => {
  const page = await browser.newPage();
  await page.emulate(iPhonex);
  await page.goto('https://www.webkul.com');
  await page.screenshot({ path: 'webkul.png'});
  await browser.close();


This is not implemented yet, please open an issue on github and I will add it
