Here is my package json file cdde.

"build": {
    "linux": {
      "target": "deb",
      "category": "Office",
      "icon": "./src/assets/icons/256x256.png"
    },
   
  }

And here is my main.js/electron.js code.

function createWindow() {
  
  const win = new BrowserWindow({
    width: 1200,
    height: 800,
    icon: path.join(__dirname, '../src/assets/icons/256x256.png'),
    webPreferences: {
      nodeIntegration: true,
      webSecurity: false,
    },
  });

}

I have tried a lot of things but nothing is working.
