wp-admin top bar button doesn't appear on mobile

Hi, I created a new button to admin top bar, but when i shrink window size it disappears as soon as the menu icon appear.

function toolbar_link_to_mypage( $wp_admin_bar ) {
   $args = array(
      'id'    => 'quick-exit',
      'title' => 'Bye',
      'href'  => wp_logout_url(),
      'parent' => 'top-secondary',
      'meta'  => array( 'class' => 'my-toolbar-page' )
   );
   $wp_admin_bar->add_node( $args );
}
add_action( 'admin_bar_menu', 'toolbar_link_to_mypage', 999 );

Can somebody please help me?
Many thanks
