fetch daje inny yinik niż kod źródłowy na stronie

Cześć,

Ponownie spotykam się z problemem, że wynik fetch-a jest inny niż html na stronie. Mam wrażenie że jest to spowodowane tym "We're sorry but ils-lookup doesn't work properly without JavaScript enabled. Please enable it to continue.", lecz nie jestem pewien. Jeżeli chodzi o to to jak zezwolić na działanie JavaScript, bo bardzo to ogranicza pracę.

wynik fetch-a:

<!DOCTYPE html><html ⚡ lang="en"><head><script async src="https://www.googletagmanager.com/gtag/js?id=G-51LVFRKJX9"></script><script>window.dataLayer = window.dataLayer || [];

Pozdrawiam

mój kod:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://ils-frequency-lookup.com/EPWA');
  await page.content();
  await browser.close();
  console.log(page);
})();

wynik:
