How does chrome work in puppeteer?

Question

PHP

How does chrome work in puppeteer, like a regular browser, or is some kind of stripped-down or special version installed there, can it be launched as a full-fledged browser, maybe what additional settings are needed, or something else ...
In the settings themselves, I specify

$browser=$puppeteer->launch(
  ['headless=false',
  'ignoreHTTPSErrors=true',
  'slowMo=2000',
  'args'=>[
      '--no-sandbox',
      '--disable-setuid-sandbox',
      '--disable-infobars',
      '--window-position=0,0',
      '--ignore-certifcate-errors',
      '--ignore-certifcate-errors-spki-list',
      '--user-agent='.$user_agent
      ]
    ]
  );
