cichy on "[Plugin: Polylang] Language switcher how to change language labels?"

Hi,

I am using language switcher in navigation menu. My question is if it is possible to change the language label e.g. from 'English' to 'EN'. I didn't find such option in the admin panel, perhaps it's possible to do it with PHP?

Thanks,
Przemek
