Use geolocation for language appearance

Hello community, 

I was wondering if it is possible or if there is a workaround to change the language of the Bookings calendar based on the viewers location. We have the standard language set to Dutch but would like the customer to use the tool in its own language. Meaning people in France get the French version, in UK an English version etc. 

Someone from the sales department told me that this should be the case on default but upon extra research I only found an option to set 1 language. Testing with people from abroad we continue to see one only that language.

Many thanks.
