Star Ratings in "Add Field" inside Field Group Editor

Hi,

I have installed your Star Ratings plugin from GitHub and then added the following snippet:

add_filter( 'rwmb_meta_boxes', 'your_prefix_register_meta_boxes' );

function your_prefix_register_meta_boxes( $meta_boxes ) {
    $prefix = '';
    $meta_boxes[] = array(
        'title'      => esc_html__( 'Star Rating', 'text-domain' ),
        'id'         => 'star-rating',
		'post_types' => ['review'],
		'context'    => 'normal',
		'fields' => array(
		array(
	            'id' 		=> 'rating',
		        'type' 		=> 'group',
		        'clone' 	=> true, // ALLOW “RATING” GROUP TO BE CLONED
		        'add_button' 	=> '+ Add Group',
				'autosave' 	=> true, // try autosave?
				'fields'     	=> array(
        		    	array(
		                'id'   => $prefix . 'name',
        		        'type' => 'text',
        		        'name' => esc_html__( 'Name', 'text-domain' ),
						'autosave' 	=> true, // try autosave?
        			),
        	    		array(
        	        	'id'   		=> $prefix . 'rating',
        	        	'type' 		=> 'rating',
        	        	'name' 		=> esc_html__( 'Rating', 'text-domain' ),
						'autosave' 	=> true, // try autosave?
        	    		),
        		),
        	),
		),
	);
    return $meta_boxes;
}

I can see the Star Rating custom field type on the post type because I specify the post_type in my code.

However, I want to make this field available in the Custom Fields "Add Field" button of the Field Group editor - screenshot for reference.

Can you please help with the correct code to achieve this?

Kind regards,
