Wait, maybe the user is referring to a real event but with a code substituted. For example, maybe there was a diplomatic code word or a secret agreement during the meeting that's referred to in some circles as "xxcxx." But I don't recall any such code from the 2022 meeting. The user might be asking for a creative story involving Commonwealth countries in 2022 with a code name. Let me consider writing a fictional story set during the CHOGM 2022 where "XXCXX" is a code for something like a secret project or a diplomatic breakthrough.
