        :param page_action: Added for automation. A function that takes the `page` object and does the automation you need.
        :param wait_selector: Wait for a specific CSS selector to be in a specific state.
        :param init_script: An absolute path to a JavaScript file to be executed on page creation for all pages in this session.

            rules. Defaults to the system default locale.
        :param timezone_id: Changes the timezone of the browser. Defaults to the system timezone.
        :param wait_selector_state: The state to wait for the selector given with `wait_selector`. The default state is `attached`.
        :param solve_cloudflare: Solves all types of the Cloudflare's Turnstile/Interstitial challenges before returning the response to you.
        :param real_chrome: If you have a Chrome browser installed on your device, enable this, and the Fetcher will launch an instance of your browser and use it.

        :param load_dom: Enabled by default, wait for all JavaScript on page(s) to fully load and execute.
        :param cdp_url: Instead of launching a new browser instance, connect to this CDP URL to control real browsers through CDP.
