To add that text to your menu, you would add a “Custom Link” menu item: https://generatepress.com/knowledgebase/using-menus/#create-drop-down-menu-custom
If you only want it to display on desktop and not mobile, you can give it the class: show-on-desktop
To add a class to a menu item, click the “Screen Options” tab at the top right of the Menus area, and check the “CSS Classes” checkbox.
