Beep boop 🤖

I noticed you didn't make any changes at the docs/ folder

• There's nothing new to document 🤔
• I'll do it later 😞

In order to keep track, I'll create an issue if you decide now is not a good time

• I just updated 🎉🎉

LGTM!

But there's also an issue that I see recurring regarding breaking SSR when new fields are added to these queries. @hiagolcm has more information on it, I'd wait for his review.
