How to change electron app icon without electron-packager?

Question

I want to create a simple desktop application on Linux(Ubuntu) and set an icon for my application. For the first time i changed it simply by icon property:

win = new BrowserWindow({width: 800, height: 600, icon: `file://${__dirname}/icon.ico`});

After that i changed its icon file, But it didn't change to new icon on Ubuntu Launcher! Its icon is the same icon which i set for the first time and it doesn't change even i remove its icon file. Can anybody help me?

Contrary to my impression this issue was an Ubuntu matter. To solve this problem go to ~/.local/share/applications then you'll see all config files with .desktop extension, now simply remove intended config file to reset application icon on Ubuntu Launcher.
