Meta box tabs - in a custom post type - wordpress

Question

Is it possible to insert meta box tabs in a specific custom post type.
I've been looking at the example :
add_filter( 'rwmb_meta_boxes', function ( $meta_boxes ) {
// 1st Meta Box
$meta_boxes[] = array(
'title' => 'Meta Box 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.
