How to block the urls during navigation to a page

Question

Using the chrome-php library https://github.com/chrome-php/chrome I'm trying to block some URLs during navigation to a web page.
From chromedevtools I've decided to use Network.setBlockedURLs method

$page->getSession()->sendMessageSync(
   new Message('Network.setBlockedURLs', [
      'urls' => [
         'example.com',
      ]
   ])
);

Am I doing that syntactically correctly or was something missed?
Also, can I specify all the subdomains with a wildcard like this *.example.com?
