Is there a way to get the list of available language shortcodes?

In order to know, which languages are available in Intercom I am used to going to

The list: https://developers.intercom.com/docs/references/rest-api/api.intercom.io/articles/article#path=translated_content

And by extracting the translated_content[language] I get a list of all the language codes possible. I am using this to validate our internal list of languages we use! But what if Intercom ever adds a new language? Is there an endpoint I could use to fetch the available languages?
