ios17 widget display area problem

I am having trouble displaying widgets on iOS17. In iOS16, it can be displayed in the full size of the widget, but in iOS17, it is displayed in an area 16 dots smaller in all direction than the original size. I would like to have the same display on iOS17 as on iOS16, is there a better way?

struct widgetSmall : View {
    var body: some View {
        ZStack() {
            Rectangle()
                .foregroundColor(Color.yellow)
            VStack() {
                HStack() {
                    Text("Upper-left")
                    Spacer()
                }
                Spacer()
                HStack() {
                    Spacer()
                    Text("Lower-right")
                }
            }
        }
    }
}
