Fix: Duplicate Google Chrome icon in Elementary OS Plank

The duplicate icons of Google Chrome on Elementary OS's Plank is a common issue. I was hoping for new Google Chrome updates but there is no fix yet.

To fix the double Google Chrome icons on the dock:

1. Open Terminal and enter:
sudo nano /usr/share/applications/google-chrome.desktop
2. Under each 3 sections,
[Desktop Entry]
[NewWindow Shortcut Group]
[NewIncognito Shortcut Group]

Insert the following code:
StartupWMClass=Google-chrome-stable





3. Press Ctrl + o and Enter to save the file.
4. Press Crtl + x to exit.
5. Now close Google Chrome and drag out the Chrome icon from dock to remove.
6. Open Google Chrome and lock the icon again.
