Localisation: what is available?

Hi,

After launching a field to help with Covid restrictions ( https://apps.garmin.com/en-IE/apps/893891d9-08e9-4bac-afee-127d5731a7b1 ) that was applicable to France as well as Ireland, I added French translations for the first time on any of my fields and... well, my first review was one I needed google translate for...

But...

 I have never seem anything other than an English language (or at least the American assault on same) fields. 

It got me thinking;

What do people see in other languages? 

How are those language searches selected?

Is there a way for me to review, say, an Italian ConnectIQ search to work out whether or not to bother translating one or more of my apps?
