@MrArnaudMichel Thanks so much for opening a PR! I'll get this triaged for review ✨

👋🏼 @MrArnaudMichel, thanks for raising a PR to close your issue! This change makes sense to me; I've just left one small comment below fixing a typo in the IDE name. After you've applied that suggestion, we'll get this merged once our repo freeze ends on October 7th 🙂

@MrArnaudMichel Thank you very much for the typo fix! ✨ This repo is currently in a code freeze, but we will get this merged as soon as the freeze ends on 10/7! 🍏

@MrArnaudMichel looks great, thanks again for your help keeping our docs up-to-date!

I misspoke earlier—as @nguyenalex836 said, we'll get this merged after the repo freeze ends on October 7th 😄
