Classic Confinement Error

I was trying to install ‘atom’ but this error popped up. I have no clue what it means. Has anyone else seen it that could explain to me what it means and what to do?

error: This revision of snap “atom” was published using classic confinement and
thus may perform arbitrary system changes outside of the security
sandbox that snaps are usually confined to, which may put your system at

   If you understand and want to proceed repeat the command including

Just do snap install atom --classic
It appears because normally snap applications exist in their own secure space and have no access to your files or system files unless specifically described, but with classic mode they are installed in a more relaxed and conventional security policy, like other applications you might install via your system’s distribution like apt-get. In this case, atom needs that special access for one reason or another so for security reasons you need to specify --classic for it to install.
