I have several questions.
I am eliminating unnecessary cords and correcting because I made a software from a sample program (SDL.Actions.Sample).

1. I would like to eliminate the button of User Ribon Group or make it unvisible.
(I'd like to leave setting of a short cut just as it is.)
When I make it as follows, only a figure of the icon has disappeared.

//-------------------------------------------DisplayMenu.cs
namespace Sdl.Actions.MyMenu
{
    #region General action

    [Action("MyMainIconAction", Icon = "")]
    [ActionLayout(typeof(MySampleRibbonGroup), 10, DisplayType.Large)]
    [Shortcut(Keys.Alt | Keys.F8)]
    public class MyMainIconAction : AbstractAction
    {
        protected override void Execute()
        {
            Form1 f = new Form1();

//---------------------------------------------

2. I made as follows so that it can also be called from context menu.
There is characters as the '_Name' behind 'MyMenu'.
How can this be deleted?

//---------------------------------------------DisplayMenuFromPopUp.cs
namespace Sdl.Actions.MyMenu
{
    [Action("MyMenu", typeof(EditorController), Icon = "")]   
    [ActionLayout(typeof(TranslationStudioDefaultContextMenus.EditorDocumentContextMenuLocation), 3, Desktop.IntegrationApi.Extensions.DisplayType.Default, "", true)]
    public class MyMainIconAction1 : AbstractAction
    {
       
        protected override void Execute()
        {
            Form1 f = new Form1();

//-----------------------------------------------
