Quest for the Ancient Cities

As you know, each and every one of the minecraft structures, at least in the overworld, has its own way of finding each other, whether they are the oceanic monuments, or the mansions in the forest, which we can get the maps through a cartographer villager, even the strong hold, that if there were no mechanics to find it through the eyes of ender, nobody would know how or where to find it, the same thing happens with the ancient cities, there is no way to find one, other than luck , and there we already have a problem, because those players who cannot find one, will not be able to experience what it is like to be in an ancient city, nor the warden, much less enjoy their loot, just as mojang had planned. So my proposal is that the witch villager has one more trade, which would be the corrupted liquid, and that its use is to be able to be crafted together with the copper to be able to make an ancient citys detector, and incidentally give it one more use to copper, and incidentally add a new search mechanic, and so it will be more fun to search for an ancient city.
