The behavior in TreeViewItem does not work

[AscendLiu]

Hello, may I ask if anyone can help me check if the DoubleTapped event of TreeViewItem is not working and there are no errors reported

    <TreeView ItemsSource="{Binding Items}"
              SelectedItems="{Binding SelectedItems}"
              SelectionMode="Multiple"
              AutoScrollToSelectedItem="False">
        <TreeView.ItemTemplate>
            <TreeDataTemplate ItemsSource="{Binding Children}">
                <StackPanel Orientation="Horizontal">
                    <PathIcon Width="16" Height="16" Data="{Binding ItemIcon}" />
                    <TextBlock Text="{Binding Header,Mode=OneTime}" VerticalAlignment="Center"
                               HorizontalAlignment="Left" Margin="2,0,0,0" />
                </StackPanel>
            </TreeDataTemplate>
        </TreeView.ItemTemplate>
        <TreeView.Styles>
            <Style Selector="TreeViewItem" x:DataType="solutionHelper:ITreeNode">
                <Setter Property="(Interaction.Behaviors)">
                    <BehaviorCollectionTemplate>
                        <BehaviorCollection>
                            <EventTriggerBehavior EventName="DoubleTapped">
                                <InvokeCommandAction Command="{Binding DoubleTappedCommand}" />
                            </EventTriggerBehavior>
                        </BehaviorCollection>
                    </BehaviorCollectionTemplate>
                </Setter>

            </Style>

        </TreeView.Styles>

    </TreeView>

VM:
public ObservableCollection<ITreeNode> Items { get; }

public interface ITreeNode
{
    public Geometry? ItemIcon { get; set; }
    public string? Header { get; set; }
    public ITreeNode? Parent { get; set; }

    public ObservableCollection<ITreeNode>? Children { get; set; }
    
    public IReadOnlyList<MenuItemViewModel>? MenuItems { get; set; }
    
    public ITreeNode AddItem(ITreeNode node);

    public void RemoveItem(ITreeNode node);

    public ICommand? DoubleTappedCommand { get; set; }
}
