❔ WPF binding expression of property from ItemsControl item with viewmodel property

public class CircleModel
{
    public Point Position { get; set; }
    public Brush Color { get; set; }
}

public class WindowViewModel
{
    public Point PositionOffset { get; set; }
    public ObservableCollection<CircleModel> Circles = new();
}

<ItemsControl ItemsSource="{Binding Circles}">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <Canvas/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Rectangle Width="512" Height="512" Fill="{Binding Color}"/>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
    <ItemsControl.ItemContainerStyle>
        <Style TargetType="ContentPresenter">
            <!--HOW TO OFFSET X AND Y BY "WindowViewModel.PositionOffset"!? Below is definitely NOT syntatically correct-->
            <Setter Property="Canvas.Left" Value="{Binding Position.X + PositionOffset.X}"/>
            <Setter Property="Canvas.Top" Value="{Binding Position.Y + PositionOffset.Y}"/>
        </Style>
    </ItemsControl.ItemContainerStyle>
</ItemsControl>
