How can I check south america SystemLanguage?

Hi

I’m working for localization.

I have European Portuguese, Brazilian Portuguese, European Spanish, South america Spanish text.

But I can not find Brazil Portuguese and South america Spanish in Unity SystemLanguage.

How can I check?

I looked up the issue, and it does not appear that SystemLanguage has those language variables.
Please take a look at this link for a complete list of SystemLanguages.
