uwp xaml - Change foreground color of back button in UWP NavigationView

Question

I try to change the foreground color of the back button in an UWP NavigationView. I managed to change all the other items in the side menu with this resources:

    <SolidColorBrush x:Key="NavigationViewItemForegroundPointerOver" Color="White"/>
    <SolidColorBrush x:Key="NavigationViewItemForegroundSelected" Color="White"/>
    <SolidColorBrush x:Key="NavigationViewItemForegroundSelectedPointerOver" Color="White"/>
    <SolidColorBrush x:Key="NavigationViewItemForegroundPressed" Color="White"/>
    <SolidColorBrush x:Key="NavigationViewItemForegroundSelectedPressed" Color="White"/>
    <SolidColorBrush x:Key="NavigationViewItemForeground" Color="White" />

    <Style x:Key="CustomNavigationMenuStyle" TargetType="Button" BasedOn="{StaticResource PaneToggleButtonStyle}">
        <Setter Property="Foreground" Value="White" />
    </Style>

What resource do I have to override for the back button?

To change the style of the back button of NavigationView, you could check the NavigationView style first.

Find the NavigationView control in Document Outline Window in Visual Studio. Then Right-click on the control, move to Edit Template and choose Edit a Copy. After that, the default style of NavigationView will be created. You could find a style called NavigationBackButtonNormalStyle. This is the default style of the back button. You could change the Foreground property as you want.

Like this:

        <Style x:Key="NavigationBackButtonNormalStyle" TargetType="Button">
        <Setter Property="Background" Value="{ThemeResource NavigationViewBackButtonBackground}"/>
        <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}"/>
        <Setter Property="FontFamily" Value="{ThemeResource SymbolThemeFontFamily}"/>
        <Setter Property="FontSize" Value="16"/>
        <Setter Property="Height" Value="{ThemeResource NavigationBackButtonHeight}"/>
        <Setter Property="Width" Value="{ThemeResource NavigationBackButtonWidth}"/>
        <Setter Property="HorizontalContentAlignment" Value="Center"/>
        <Setter Property="VerticalContentAlignment" Value="Center"/>
        <Setter Property="UseSystemFocusVisuals" Value="{StaticResource UseSystemFocusVisuals}"/>
        <Setter Property="Content" Value="&#xE72B;"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Grid x:Name="RootGrid" Background="{TemplateBinding Background}">
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">
                                <VisualState x:Name="Normal"/>
                                <VisualState x:Name="PointerOver">

                                            <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource NavigationViewButtonBackgroundPointerOver}"/>
