Hello,

If possible to add to it an 'undo' menu item.

Yes, you can create a EditorHandler and add CustomSelectionActionModeCallback

        Microsoft.Maui.Handlers.EditorHandler.Mapper.AppendToMapping("MyCustomization", (handler, view) =>
            {
#if ANDROID
                handler.PlatformView.CustomSelectionActionModeCallback = new MyCustomSelectionActionModelCallBack();


#endif
            });

Next, please create class called MyCustomSelectionActionModelCallBack.cs. Then you can add menu in the OnCreateActionMode and handle the undo menu click event in the OnActionItemClicked method.

#if ANDROID
    internal class MyCustomSelectionActionModelCallBack : Java.Lang.Object, ActionMode.ICallback
    {
        public bool OnActionItemClicked(ActionMode? mode, IMenuItem? item)
        {
            if(item.ItemId ==10086)
            {
                //handle your undo operation
            }
            return false;
        }

       public bool OnCreateActionMode(ActionMode? mode, IMenu? menu)
        {
            //add undo Menu
            menu.Add(0, 10086, 0, "Undo");


           return true;
        }

       public void OnDestroyActionMode(ActionMode? mode)
        {
           
        }
        public bool OnPrepareActionMode(ActionMode? mode, IMenu? menu)
        {
           
            return false;
        }
    }
#endif
