            ->addAction(Action::new('action1')->linkToCrudAction('doAction1'))
        ;

        return parent::configureActions($actions)
            ->add(Crud::PAGE_INDEX, $notifGroupActions)
            ->add(Crud::PAGE_DETAIL, $notifGroupActions)
        ;
    }

        return $this->redirect($adminContext->getRequest()->headers->get('referer'));
    }

            ->update(Crud::PAGE_INDEX, 'action1', fn (ActionGroup $a) => $a->addAction($action2))
            ->update(Crud::PAGE_DETAIL, 'action1', fn (ActionGroup $a) => $a->addAction($action2));
    }

    #[AdminRoute(path: '/{entityId}/doAction2', name: 'doAction2')]
    public function doAction2(AdminContext $adminContext, FirebaseService $firebaseService): RedirectResponse
    {
        // ...
