Set language of recaptcha

[ar-anvd]

I can't find an answer in SO, so let me post here.

There is any way to set a language without using RECAPTCHA_PARAMETERS = {'hl': 'zh'} ?

This will ignore the @babel.localeselector, so in a multilingual site when I change the localeselector the recaptcha remains in the same language (api.js).
