currency switcher to top bar

Hi,

I’m trying to add the currency switcher to the top bar of my website.

When trying to edit my top bar menu it doesn’t give me to option to add it in as a widget or any text/html space for a short code – only other way I can think i’ll be able to add it is with a custom link? Can you provide any assistance with this?

I’m working on a staging site at the moment so that’s the page link

The page I need help with: [log in to see the link]
