Minecraft 1.20 new installation: worlds not present in "saves" folder

Hi, I recently re-installed minecraft after a long time not playing it. I'm using Manjaro linux as OS, which is different from the Linux distro I used in the past to play minecraft (I think it was Ubuntu). I have my old worlds (from v1.16) saved under ~/.minecraft/saves and I hoped they would appear again in the new installation after restoring this folder, but this isn't the case. Also, I created a new world in the new installation but it doesn't appear in the ~/.minecraft/saves folder. Where should I look for it? Is the location of the minecraft folder changed with the new releases?
