Remove user's access to .config and Library folders

I used the following commands to give myself access to the .config folder in order to access Google Chrome's internal files. sudo chown user ~user/.config chmod 711 ~user/.config That did not give me access to the .config folder, but it gave me access to the Library folder. I am not sure what the relationship between those two folders is, but that's where the Chrome files ended up being located. Having access to the Library folder is now interfering with my work, because lots of unneeded files are turning up in Finder searches now, and I would like to reverse those commands. My username on MacOS is user (I realize it's probably not the best practice), and that account is also the machine's admin. How do I reverse both ownership and chmod modifications made earlier?
