How to set application icon in eletron-vue js - vuejs2

Question

I am working with electron-vue js for building cross platform desktop app.
I want to set custom icon when i make build file and want to add product name on app.
But when i set custom icon, it work perfect in locally but when make it build then not work correctly.
It give an error default Electron icon is used reason=application icon is not set.
Here is Background.js file
'use strict'
import { app, protocol, BrowserWindow } from 'electron'
import { createProtocol } from 'vue-cli-plugin-electron-builder/lib'
import installExtension, { VUEJS_DEVTOOLS } from 'electron-devtools-installer'
const isDevelopment = process.env.NODE_ENV !== 'production'
// Scheme must be registered before the app is ready
protocol.registerSchemesAsPrivileged([
{ scheme: 'app', privileges: { secure: true, standard: true } }
])
async function createWindow() {
const path = require('path')
const win = new BrowserWindow({
webPreferences: {
icon: path.join(__dirname, '../public/favicon.ico'),
// Use pluginOptions.nodeIntegration, leave this alone
// See nklayman.github.io/vue-cli-plugin-electron-builder/guide/security.html#node-integration for more info
nodeIntegration: process.env.ELECTRON_NODE_INTEGRATION
}
})
win.maximize();
win.removeMenu();
//win.setIcon(path.join(__dirname, '../public/favicon.ico'));
if (process.env.WEBPACK_DEV_SERVER_URL) {
// Load the url of the dev server if in development mode
await win.loadURL(process.env.WEBPACK_DEV_SERVER_URL)
if (!process.env.IS_TEST) win.webContents.openDevTools()
} else {
createProtocol('app')
// Load the index.html when not in development
win.loadURL('app://./index.html')
}
}
// Quit when all windows are closed.
app.on('window-all-closed', () => {
// On macOS it is common for applications and their menu bar
// to stay active until the user quits explicitly with Cmd + Q
if (process.platform !== 'darwin') {
app.quit()
}
})
app.on('activate', () => {
// On macOS it's common to re-create a window in the app when the
// dock icon is clicked and there are no other windows open.
if (BrowserWindow.getAllWindows().length === 0) createWindow()
})
// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', async () => {
if (isDevelopment && !process.env.IS_TEST) {
// Install Vue Devtools
try {
await installExtension(VUEJS_DEVTOOLS)
} catch (e) {
console.error('Vue Devtools failed to install:', e.toString())
}
}
createWindow()
})
// Exit cleanly on request from parent process in development mode.
if (isDevelopment) {
if (process.platform === 'win32') {
process.on('message', (data) => {
if (data === 'graceful-exit') {
app.quit()
}
})
} else {
process.on('SIGTERM', () => {
app.quit()
})
}
}
And Package.Json is

When we work in electron vue js. we add new file vue.config.js and paste these line of code.
module.exports = {
pluginOptions: {
electronBuilder: {
builderOptions: {
productName: "News App",
appId: 'test.com',
win: {
"target": [
"nsis"
],
icon: 'public/svg.png',
"requestedExecutionLevel": "requireAdministrator"
},
"nsis": {
"installerIcon": "public/favicon.ico",
"uninstallerIcon": "public/favicon.ico",
"uninstallDisplayName": "CPU Monitor",
"license": "license.txt",
"oneClick": false,
"allowToChangeInstallationDirectory": true
}
},
},
},
}
