How to make 2 menu items in sleepingowl from one model?

Question

Laravel

Hello!
I have a Services model. The object of this model has a parent_id field, those with parent_id = 0 are parent categories.
I can somehow display nesting using the same model:
Services
- Categories (only parent_id = 0 will be displayed here)
- Services themselves (all with parent_id > 0)

use SleepingOwl\Admin\Navigation\Page;

    [
        'title' => 'Пользователи',
        'icon'  => 'fa fa-users',
        'pages' => [
