Wordpress dynamic sidebar without title

Question

I'd like to pull in a dynamic sidebar. I have 1 text item in the widget sidebar but I DON't want to pull in widget the title (just the body). Can anyone show me where WordPress is pulling in the Title?

e.g. At the moment I have...

// In my page template...
<div id='advert-header'>        
   <?php dynamic_sidebar( 'Header Advert' ); ?>
</div>

// In functions.php...
function twentyten_widgets_init() {
    register_sidebar( array(
        'name' => __( 'Header Advert', 'twentyten' ),
        'id' => 'primary-widget-area',
        'description' => __( 'The primary widget area', 'twentyten' ),
        'before_widget' => '',
        'after_widget' => '',
        'before_title' => '',
        'after_title' => '',
    ) );
// etc.
}

Those titles can be useful for CMS user, so in your register_sidebar, you can put sth. like I did in code below (works in Wordpress 5.0.3). Now widgets title is in html comment, it seems ok for me

  register_sidebar( array(
    'name'          => esc_html__( 'Contact page widgets', 'xxx' ),
    'id'            => 'sidebar-3',
    'description'   => esc_html__( 'Add widgets here to appear on contact page.', 'xxx' ),
    'before_widget' => '<div id="%1$s" class="widget %2$s">',
    'after_widget'  => '</div>',
    'before_title'  => '<!-- ',
    'after_title'   => ' -->',
) );
