Meta box tabs in a custom post type

Is it possible to insert meta box tabs in a specific content post type.
I've been looking in the example :

add_filter( 'rwmb_meta_boxes', function ( $meta_boxes ) {
    // 1st Meta Box
    $meta_boxes[] = array(
        'title'     => 'MB Tabs Demo',

        // List of tabs, in one of the following formats:
        // 1) key => label
        // 2) key => array( 'label' => Tab label, 'icon' => Tab icon )
        'tabs'      => array(
            'contact' => array(
                'label' => 'Contact',
                'icon'  => 'dashicons-email', // Dashicon
            ),
            'social'  => array(
                'label' => 'Social Media',
                'icon'  => 'dashicons-share', // Dashicon
            ),
            'note'    => array(
                'label' => 'Note',
                'icon'  => 'https://i.imgur.com/nJtag1q.png', // Custom icon, using image
            ),
        ),

        // Tab style: 'default', 'box' or 'left'. Optional
        'tab_style' => 'default',

        // Show meta box wrapper around tabs? true (default) or false. Optional
        'tab_wrapper' => true,

        'fields'    => array(
            array(
                'name' => 'Name',
                'id'   => 'name',
                'type' => 'text',

                // Which tab this field belongs to? Put tab key here
                'tab'  => 'contact',
            ),
            array(
                'name' => 'Email',
                'id'   => 'email',
                'type' => 'email',
                'tab'  => 'contact',
            ),
            array(
                'name' => 'Facebook',
                'id'   => 'facebook',
                'type' => 'text',
                'tab'  => 'social',
            ),
            array(
                'name' => 'Note',
                'id'   => 'note',
                'type' => 'textarea',
                'tab'  => 'note',
            ),
        ),
    );

This will work in post if added to functions.php ... but if we try to use it in a custom post type the metabox will appear but the fields will not.

Any help would be appreciated.
