I believe the way to do this is as follows:
– Dashboard > Appearance > Menus and create a new menu with items you want in the Secondary Menu.
– You can create an e-mail link and phone number link by adding a Custom Link, use # for URL and add
<a href="mailto:YOUR_EMAIL">LINK_TEXT</a> <a href="tel:YOUR_PHONE_NUMBER">LINK_TEXT</a>
– Next go into Customizer > Menu > Menu Locations > Select the menu you just created in Secondary Menu
– Then you can style it in Customizer > Layout > Secondary Navigation.
Let me know if this helps!
