Add custom field from checkout manager plugin

Hi,
I am using your plugin for printing delivery notes.
However, during the checkout I have added a singole custom field. This was done by using the plugin ‘Checkout Manager’. I need that field in the printed note, so I add the following code to the function.php of my theme:

(wooccm0 is the name of the new field)

function example_custom_order_fields( $fields, $order ) {
    $new_fields = array();
        
    if( get_post_meta( $order->id, 'wooccm0', true ) ) {
        $new_fields['wooccm0'] = array( 
            'label' => 'Codice ISS',
            'value' => get_post_meta( $order->id, 'wooccm0', true )
        );
    }
    
    return array_merge( $fields, $new_fields );
}
add_filter( 'wcdn_order_info_fields', 'example_custom_order_fields', 10, 1 );

However, when I print the order I am still not able to see the new field.
How can I do?

Thanks for help
