This code creates an instance of the Chrome web browser...

This code creates an instance of the Chrome web browser with specified options. It then uses the Chrome DevTools Protocol (CDP) to execute a command that adds a script to the page that will be evaluated whenever a new document is created. The script defines a new property "webdriver" on the "navigator" object and sets its value to "undefined". This is commonly used to bypass automated detection of WebDriver-controlled browsers, which may be blocked by some websites.
