Emulate landscape iPad orientation in chrome

Following code runs iPad emulation in Chrome in portrait orientation.
How can I change it to get landscape orientation?

const {Builder, By, until} = require('selenium-webdriver');
const chrome = require('selenium-webdriver/chrome');

var driver = new Builder()
  .forBrowser('chrome')
  .setChromeOptions(new chrome.Options()
    .setMobileEmulation({deviceName: 'Apple iPad'})
    .addArguments('start-maximized')
  ).build();
