How can i remove the titlebar of my MAUI Blazor Application?

I m trying to make a maui application using blazor (html) for my design. I want to remove the titlebar of my application and make my application a bit rounded, but I dont know how I can start doing it. i did not found any information about it.

protected override Window CreateWindow(IActivationState activationState)
{
   return new Window()
   {
      Title = "MyApp",
      Page = MainPage,
   };
}

there is no option to set the titlebar.
