Language flags in navigation

Hi there,

i would like to have my language flags in the navigation bar. They are in it now and in a great spot just by using the language switcher in the menu section of wordpress. https://imgur.com/W4CUpdq
And again i love the placing of the flags but when i resize my screen it will become a hamburger menu and the flags will go inside it.

I would like to somehow keep showing these on the outside. Any tips?
