Extend ADMIN_ROLE not working?

I am using arckinteractive's role plugin (https://github.com/arckinteractive/Roles/tree/master), I wanna create a moderator role and I also had a look at the roles_moderator plugin, but it is pretty old. The code looks all right, so I used it in my plugin: 

​$roles = [
        MODERATOR => [
            'title' => 'Moderator',
            'extends' => [
                ADMIN_ROLE
            ],
            'menus' => [],
            'permissions' => [],
        ],
        ......
];

but this is not working. I cannot see the admin menu on topbar and also not see other admin content, like editing other entities. Can anyone help? thanks
