Resource in Navigation Menu

[exotic magnet]

I am upgrading Custom Tool from Nova 3 to Nova 4. We have our Navigation menu populated from renderNavigation() method of Tool class.

Now I understand, we have to use menu() instead. So:

    public function menu(Request $request)
    {
        return MenuSection::make('Section')
            ->path('/resources/foo')
            ->icon('server');
    }

Above works. It works even when I use MenuGroup and MenuItem

But doesn't work, when I use resource

MenuSection::make('Section', [
    MenuGroup::make('Bar', [
        MenuItem::resource(Foo::class),
    ]),
])

In resource, I have these property set:

    /**
     * The logical group associated with the resource.
     *
     * @var string
     */
    public static $group = 'Bar';

    /**
     * This resource is not displayed in navigation
     */
    public static $displayInNavigation = true;

Any guesses where am I going wrong? I don't get any errors in console or error log file.

have you check this https://nova.laravel.com/docs/4.0/upgrade.html#updating-third-party-nova-packages?

return MenuSection::make(Nova::__('Inventory Online'), [
            MenuGroup::make(Nova::__('Document'), [
                MenuItem::resource(DocumentType::class),
                MenuItem::resource(Document::class),
                MenuItem::resource(DocumentItem::class),
            ])->collapsedByDefault(),
            MenuGroup::make(Nova::__('Mutation'), [
                MenuItem::resource(BahanBakuDanPenolong::class),
                MenuItem::resource(BarangDalamProses::class),
                MenuItem::resource(BarangJadi::class),
                MenuItem::resource(BarangSisaDanScrap::class),
                MenuItem::resource(BarangSparepart::class),
                MenuItem::resource(MesinDanPeralatanKantor::class),
            ])->collapsedByDefault(),
            MenuItem::resource(Upload::class),
        ])->icon('document');

works on me
