Sims 4 Studio Language Translation Mistakes

Is there a way to help with the translations nowadays? I found the mega files that were shared by andrew on page 9 of this thread but when I click on it there is nothing on mega. Are these spread sheets still available? Or is there some other way to help with the translations? For German there are a lot of strings missing that need translations and I would be willing to do that. However, I couldn't find a way to easily extract the needed strings.
So: What's the best way to provide translations? And are they even implemented? The last post that confirmed implemenation is from August 2022. If there is an easy way to translate S4S it may be wise to put a tutorial for it in the first post of this thread so everyone can find it easily
