For that website, get a Chrome plugin called User Javascript and CSS and set it up to inject:

    #hello_banner { display:none !important; }
    .grecaptcha-badge { display: none !important; }

I know it's a lot of work to inspect the DOM and do this for every site but I just hate banners and popups that much, and very often multiple websites reuse the same banner code so my efforts start paying off after dealing with a few dozen.
