React app for Lg signage 55uh5n-e

Hello! I have created a React web app and am currently hosting it on a microsoft IIS webserver. Sadly I can´t see the web app on the monitor. When i use a plain index.html, without react, it works fine, so the webserver isn´t an issue. Is the monitor compatible with React applications or is there anything I should look out for when doing this? I would like to have my React app shown on the monitor using the url function.
