That's cool, I like it! I'm currently working on the Hungarian translation, according to Weblate it's 55% done. I have the same username there.

Edit: there was an issue and the weblate got locked. I've fixed it now.

Oh, all right. Thanks!

I would like to help, but I can't find an option to add a new language. Am I missing something?

Ubuntu. If I remember correctly it was in 2016. I do remember that it was still using the Unity desktop environment, which was pretty good in my opinion. I didn't know anything about Linux back then, and I tried to run Minecraft on it through WINE. It didn't work lol.
