WPF 数据绑定上下文 ItemsControl 内 DataTemplate 中的按钮菜单

我正在尝试弄清楚如何绑定正在添加到我拥有的 ItemsControl 中的按钮的上下文菜单。基本上，我希望能够右键单击一个按钮并将其从位于我的视图模型上的可观察集合中删除。我知道 ContextMenu 不是 VisualTree 的一部分，所以使用 RelativeSource 沿着树向上走去查找我的 DataContext 对我没有用。

我想做的最终目标是将菜单项上的命令绑定到我的 ViewModel 上的删除命令，然后传入您右键单击的按钮的 Content 属性，以便我可以将其从可观察集合中删除。

对此的任何帮助将不胜感激。

型：

public class Preset
{
    public string Name { get; set; }
}

视图模型：

public class SettingsWindowViewModel
{
    public ObservableCollection<Preset> MyPresets { get; } = new ObservableCollection<Preset>();
    private ICommand _plusCommand;
    public ICommand PlusCommand => _plusCommand ?? (_plusCommand = new DelegateCommand(AddPreset));
    private ICommand _removeCommand;
    public ICommand RemoveCommand => _removeCommand ?? (_removeCommand = new DelegateCommand<string>(RemovePreset));
    private void AddPreset()
    {
        var count = MyPresets.Count;
        MyPresets.Add(new Preset {Name = $"Preset{count+1}"});
    }
    private void RemovePreset(string name)
    {
        var preset = MyPresets.FirstOrDefault(x => string.Equals(x.Name, name, StringComparison.CurrentCultureIgnoreCase));
        if (preset!= null)
        {
            MyPresets.Remove(preset);
        }
    }
}
