Column not taking all available space from it's parent Column

Question

Column(
     modifier = Modifier.fillMaxSize().background(Color.Green)
) {
     Column(
        modifier = Modifier.fillMaxSize().background(Color.Red)
     ) {}
}

This child Column is not taking any space from it's parent Column

I want this column to fill the full available space

Any ideas about how to do this?
