如何轻松隐藏UWP MediaPlayerElement中的所有传输控件？

<MediaPlayerElement AreTransportControlsEnabled="False" />

<Grid>
    <MediaPlayerElement x:Name="mediaPlayer" AreTransportControlsEnabled="False" />
    <Button Click="PlayPauseButton_Click" Content="播放/暂停" />
    <Slider x:Name="progressSlider" ValueChanged="ProgressSlider_ValueChanged" />
</Grid>

private void PlayPauseButton_Click(object sender, RoutedEventArgs e)
{
    if (mediaPlayer.CurrentState == MediaElementState.Playing)
    {
        mediaPlayer.Pause();
    }
    else
    {
        mediaPlayer.Play();
    }
}

private void ProgressSlider_ValueChanged(object sender, RangeBaseValueChangedEventArgs e)
{
    mediaPlayer.Position = TimeSpan.FromSeconds(progressSlider.Value);
}
