Unlimited elements plugin template import not showing in Elementor, what should I do?

Question

WordPress

In versions of Elementor after 3.1.4, template imports are no longer displayed, this is corrected by the code in functions.php in the theme or through the Theme Customization plugin, which allows you to add code to it without creating a child theme.

add_action('admin_head', 'my_custom_styles');
function my_custom_styles() {
  echo '<style>
    #e-admin-top-bar-root~#wpbody .wrap .page-title-action,#e-admin-top-bar-root~#wpbody .wrap h1 {
  display:inline;
  }
  </style>';
}
