Sorry but it seems not support browserless with ws. I got the following error:

(node:81727) UnhandledPromiseRejectionWarning: TypeError: page.browser is not a function at Plugin.onPageCreated (/Users/chandler/projects/wondershare/aps_crawler/nodejs/node_modules/puppeteer-extra-plugin-anonymize-ua/index.js:42:25) at Plugin._onTargetCreated (/Users/chandler/projects/wondershare/aps_crawler/nodejs/node_modules/puppeteer-extra-plugin/dist/index.cjs.js:518:28) at process._tickCallback (internal/process/next_tick.js:68:7) (node:81727) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

by using code as follow:

const puppeteer = require("puppeteer-extra")
const pluginStealth = require("puppeteer-extra-plugin-stealth")
puppeteer.use(pluginStealth());
const browser = await puppeteer.connect({browserWSEndpoint: this.browserWSEndpoint});
let page = await browser.newPage();
