This would involve some template customization which goes beyond the scope of our support as this feature is not available out of the box in the theme but I could help you get started.
You will have to do this through a child theme. You can fine more information about the template file customization here:
The file that you need to override is _navbar.php that is in /wp-content/themes/x/framework/legacy/cranium/headers/views/global/
You can add the content with the html in that file then you can add custom CSS to style the added content.
Hope this helps you get started.
