Hello,
Thank you for using our theme.
To add such a link, we need to add the link to our primary menu & add CSS classes to that menu item. Use the following menu classes:
1. align-them-right – To align following menu items to the right.
2. highlight-this-menu-item – To highlight the menu item.
On our demo website, we have added these classes to the ‘Contact Us’ menu item. Please check the screenshot. https://imgur.com/ZgKmrIa
If you can’t see option to add classes to menu item, you can enable it from ‘Screen Options’ on upper right corner. Check Screenshot
We are still in the process of adding documentation for this. It will be on our site soon.
