Hi @yahya-mouman! Since that's the case, I'll go ahead and remove documentation from the reviewer's list. If anything changes and you need us to review, feel free to add us back.

No review needed. I couldn't remove documentation from the reviewer's list 🙃 so am commenting so that I can remove it from our PR queue.
