title: JetBrains Compose for Desktop title bar background color or dark mode
body: <p>Is there a way in JetBrains Compose for Desktop to change the title bar background color or just change it for dark mode? I'm using MacOS, so the bar can be light or dark. It would also be fine to make titlebar itself invisible (but keep the close, minimise and maximise buttons) and create your own view below it.</p>
  <p>I was looking in the compose window code, but couldn't find it there.</p>
