       This function obtains an authentication token from the cookies of a given URL.

       The function specifically uses the Chromium web browser through the playwright library
       to open the specified URL, accepts the site's cookies, and then extracts any potential
       authentication tokens present in these cookies.

       Args:
           url (str): The URL from which the authentication token will be extracted.
           btn (str): CSS selector of `Accept Cookies` button on page

       Returns:
           str: The extracted authentication token. If no auth token found, it returns empty string.
