Can't find the new folder where worlds go now

I can't find the new folder that worlds are supposed to get stored at now, so everytime I go back to 1.17.40, all of the worlds that I created in versions beta 1.18.0.22 and 1.18.0.23 gets deleted, idk if it's something to do with my phone or not but I can't find the new world folder.

Please fix
