    public function __construct(Plugin $plugin)
    {

        add_action(

            array($this, 'enqueue_scripts_public')
        );
    }

    public function enqueue_scripts_public(){
        $scripts = $this->plugin->get_admin_scripts();
        $name = $this->plugin->name . '_twind_admin';
        wp_enqueue_script($name, $scripts['main']);
        wp_add_inline_script($name, $scripts['setup']);
    }
