Unlike other world quests in the game, you have to complete the Fishing for the Jade world quest before proceeding with this quest. You have to be Adventure rank 40 or above and complete Ganyu's story quest to get Fishing for the Jade world quest. Millelith guard Kun would be the NPC who will give you both of these world quests, and you can find him patrolling the liyue harbor. Sometimes, with new updates, Hoyoverse adds new world quests in the regions, and you can complete them at your own leisure. I suggest you complete both of these world quests, Fishing for the Jade and Return of the Jade chamber, as they give you information about the aftermath of a clash between Osial and Liyue.
