Contextmenu add/remove items on specific elements

I have added a custom contextmenuitem but I only want it to be displayed on a specific element not everywhere, how is this possible? Currently it is shown on every element when i rightclick.

My current code includes this:

CKEDITOR.plugins.add('newplugin',
        {
            requires: ['htmlwriter'],
            init: function(editor) {

                var pluginName = 'newplugin';
                editor.addCommand('abbrDialog', new CKEDITOR.dialogCommand('abbrDialog'));
                editor.ui.addButton('Newplugin',
                        {
                            label: 'Försäkringsinnehav',
                            command: 'abbrDialog',
                            icon: 'templates'
                        });

                editor.addMenuGroup('abbrGroup');
                editor.contextMenu.addListener(function(element, selection) {
                    return {
                        myCommand: CKEDITOR.TRISTATE_OFF
                    };
                });

                editor.addMenuItems({
                    myCommand: {
                        label: "Edit properties",
                        command: 'abbrDialog',
                        group: 'abbrGroup',
                        order: 1
                    }});

                editor.removeMenuItem('image');
                

                editor.on('doubleclick', function(evt)
                {
                    evt.data.dialog = 'abbrDialog';

                });

                editor.dataProcessor = new CKEDITOR.customprocessor(editor);

            }
        });

How can I make the contextmenuchanges only appear on a specific element?
