How to add a second button to navigation 7.1

Site URL: https://www.niche.wedding/

Hi, I'm trying to add a second button to my navigation, underneath the current button. Is there any code that I can use to so this? 

Thanks

Hi, I'm in the wedding business too, your website looks lovely 🙂

Do you mean you want the "Be Social With Us" button below the "Get in Touch" button?

Thanks,
