How to customize existing toolbar in DocumentEditorContainer

DocumentEditorContainer allows you to customize(add, show, hide, enable, and disable) existing items in a toolbar.

• Add - New items can defined by CustomToolbarItemModel and with existing items in toolbarItems property. Newly added item click action can be defined in toolbarClick.

• Show, Hide - Existing items can be shown or hidden using the toolbarItems property. Pre-defined toolbar items are available with ToolbarItem.

• Enable, Disable - Toolbar items can be enabled or disable using enableItems

let toolItem: CustomToolbarItemModel = {
    prefixIcon: "e-de-ctnr-lock",
    tooltipText: "Disable Image",
    text: onWrapText("Disable Image"),
    id: "Custom"
};

//Initialize Document Editor Container component with custom toolbar item.
let container: DocumentEditorContainer = new DocumentEditorContainer({
    toolbarItems: [toolItem, 'Undo', 'Redo', 'Separator', 'Image', 'Table', 'Hyperlink', 'Bookmark', 'TableOfContents', 'Separator', 'Header', 'Footer', 'PageSetup', 'PageNumber', 'Break', 'InsertFootnote', 'InsertEndnote', 'Separator', 'Find', 'Separator', 'Comments', 'TrackChanges', 'Separator', 'LocalClipboard', 'RestrictEditing', 'Separator', 'FormFields', 'UpdateFields','ContentControl']
});
container.appendTo('#container');
//To handle custom toolbar click event.
container.toolbarClick = (args: ClickEventArgs): void => {
    switch (args.item.id) {
        case 'Custom':
            //Disable image toolbar item.
            container.toolbar.enableItems(4, false);
            break;
    }
};

function onWrapText(text: string): string {
  let content: string = '';
    const index: number = text.lastIndexOf(' ');

    if (index !== -1) {
        content = text.slice(0, index) + "<div class='e-de-text-wrap'>" + text.slice(index + 1) + "</div>";
    } else {
        content = text;
    }

    return content;
}
