 * A Browser is created when Puppeteer connects to a Chromium instance, either through

 *
 * @example
 *
 * An example of disconnecting from and reconnecting to a {@link Browser}:

 * const puppeteer = require('puppeteer');
 *
 * (async () => {

 *   // Store the endpoint to be able to reconnect to Chromium
 *   const browserWSEndpoint = browser.wsEndpoint();
