Thanks for sharing this snippet!

For Google Chrome user, run this instead to applying the icons:

for s in {32,48,64,96,128}; do xdg-icon-resource install --size ${s} --context apps ~/.config/google-chrome/Default/Extensions/ophjlpahpchlmihnnnihgmmeilfjmjjc/*/res/img/line_logo_${s}x${s}_on.png naver-line; done

To install, copy the file into ~/.local/share/applications.
You can append Categories=GNOME;GTK;Network;InstantMessaging; to the file to make it show up in the right menu category.
