如何在Xbox上改变MediaPlayerElement的滑块样式？

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

    <Style x:Key="CustomSliderStyle" TargetType="Slider" BasedOn="{StaticResource DefaultSliderStyle}">
        <!-- Customize the slider appearance here -->
        <Setter Property="Background" Value="Red" />
        <Setter Property="Foreground" Value="White" />
        <Setter Property="BorderBrush" Value="Black" />
        <Setter Property="BorderThickness" Value="2" />
        <!-- Add more setters to customize other properties as needed -->
    </Style>

</ResourceDictionary>
