Load HTML String
For a simple UI, you can directly load an HTML string, for example, an interface generated by AI.
public class TestScript : MonoBehaviour
{
    public EdgeCanvas m_edgeCanvas;
     
    private async void Awake()
    {
        m_edgeCanvas.WaitInitialize((canvas) =>
        {
            canvas.LoadHtmlContent(@"<h1 style=""color:red"">Hello UWebView2</h1>")
        });
    }
}npm
