How can I uninstall a package or program so that it will reset all settings on subsequent installation?

Question

ubuntu

sudo apt-get purge

(or

sudo apt remove

) +

sudo apt-get autoremove

does not help in any way to remove the atom so that on subsequent boot it will reset the settings and install without plugins, by default.
I first installed it from the repository

sudo apt update
sudo apt install software-properties-common apt-transport-https wget

wget -q https://packagecloud.io/AtomEditor/atom/gpgkey -O- | sudo apt key add -

sudo add-apt-repository "deb [arch=amd64] https://packagecloud.io/AtomEditor/atom/any/ any main"

sudo apt install atom

When I saw that it had reinstalled from the repository with the same plugins, I decided to install it from the official site, opened the package, but nothing helped
PS Ubuntu 18.04

Installing and uninstalling a package does not affect its settings in your home in any way.
Find where you have them stored and delete them. You don't need to touch the package.
Most likely, the configs are stored approximately there:
Or if the atom does not follow the standard ~/.atom
If you do not find it there, then look in the docks where it stores all the settings.
