如何将app.user数据分配给SonataAdminBundle SideMenu

sonata_admin:
    dashboard:
        groups:
            app_user_group:
                label: App User
                items:
                    - app_user_list
    side_menu:
        - { label: App User, route: 'admin_app_user_list' }

<?php

namespace App\Admin;

use Sonata\AdminBundle\Admin\AbstractAdmin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Form\FormMapper;

class AppUserAdmin extends AbstractAdmin
{
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
            ->add('username')
            ->add('email')
            // Add more fields as per your requirements
        ;
    }

    protected function configureListFields(ListMapper $listMapper)
    {
        $listMapper
            ->addIdentifier('username')
            ->add('email')
            // Add more fields as per your requirements
        ;
    }
}

sonata_admin:
    dashboard:
        groups:
            app_user_group:
                label: App User
                items:
                    - app_user_list
    side_menu:
        - { label: App User, route: 'admin_app_user_list' }
    admin_services:
        app.admin.app_user:
            class: App\Admin\AppUserAdmin
            tags:
                - { name: sonata.admin, manager_type: orm, group: app_user_group, label: App User }
            arguments:
                - ~
                - App\Entity\User
                - ~
