PhastPress not working with Retainful scripts

We use a plugin called Retainful for our WooCommerce site.

I added “phast_no_defer” for the “rnoc_track-user-cart” script. It works, but the wp_localize_inline script tag is not set to phast_no_defer. What do I do?

Hope that makes sense. Here’s the relevant function in the plugin:

/**
     * Adding the script to track user cart
     */
    function addCartTrackingScripts()
    {
        if (!wp_script_is('wc-cart-fragments', 'enqueued')) {
            wp_enqueue_script('wc-cart-fragments');
        }
        if (!wp_script_is(RNOC_PLUGIN_PREFIX . 'track-user-cart', 'enqueued')) {
            wp_enqueue_script(RNOC_PLUGIN_PREFIX . 'track-user-cart', $this->getAbandonedCartJsEngineUrl(), array('jquery'), RNOC_VERSION, false);
            $user_ip = $this->getClientIp();
            $user_ip = $this->formatUserIP($user_ip);
            $data = array(
                'ajax_url' => admin_url('admin-ajax.php'),
                'version' => RNOC_VERSION,
                'public_key' => self::$settings->getApiKey(),
                'api_url' => self::$api->getAbandonedCartEndPoint(),
                'tracking_element_selector' => $this->getTrackingElementId(),
                'cart_tracking_engine' => self::$settings->getCartTrackingEngine()
            );
            $data = apply_filters('rnoc_add_cart_tracking_scripts', $data);
            wp_localize_script(RNOC_PLUGIN_PREFIX . 'track-user-cart', 'retainful_cart_data', $data);
        }
    }
