It looks ok. Two notes:

• I am not sure if oc is the right language code or if we will have to use some form of ES_oc - will investigate. That's just to go sure and due to my own knowledge deficits. This is connected to ISO 639-1, but it's more about working in connection with Hugo.
• You have a "Recent" there in the third group (line 8). Is that because there is no wording for that or did you miss it? I assume it's not Occitania?

Also, I am starting to attribute "code ownership" for translations to the people who translated it. Are you ok to be attributed with ensag-dev in .github/CODEOWNERS? The concept is explained here in the docs. Basically you own the translation, because no one else (except anyone adding changes later on) knows the language ;)

PS: ignore the Netlify deploy errors. That's a config issue.

Hello,

the iso code would be oc_FR, oc_ES or oc_IT, the language code then the country.
Yes "recent" is the same in Occitan :)

I am merging this. The RFC Hugo is using is RFC5646 and oc is in there.
