Why is my report empty when embedded in JavaFX app?

Hi all, 

When I embed the URL into my JavaFX app to load in a WebView, I see the report loading part but then it is just all white. Every other webpage shows fine. Does anyone know why my reports are not showing, while when I enter the URL in the browser directly everything shows up fine.

My code :

WebView webView = new WebView();
        WebEngine webEngine = webView.getEngine();
         webEngine.load("https://app.powerbi.com/view?r=eyJrIjoiMzdiNGIzOWMtOGFiMi00YTc0LWFhYmYtZjcyN2E3YzljYTY1IiwidCI6IjQzY2Q3MWNlLTBjODYtNGMxZi05NTc1LTBlMzg4YWEwZDY4YiIsImMiOjh9");

Thanks in advance
