DevTools was disconnected from the page, electron

Guys i need to open some web application into my electron app, i used <webview> tag but [official docs][1] of electron offers to use BrowserView.
so i used BrowserView, BUT i got DevTools was disconnected from the page error!
simply i need DevTools for my BrowserView not my entire app. what should i do?

myCode: just main.js

const {app, BrowserView, BrowserWindow} = require('electron');

let win;
let view;
app.on('ready', () => {
    win = new BrowserWindow({width: 800, height: 600});
    win.on('closed', () => {
        win = null
    });
    view = new BrowserView({
        webPreferences: {
            nodeIntegration: false
        }
    });
    win.setBrowserView(view);
    view.setBounds({x: 0, y: 0, width: 800, height: 600});
    view.webContents.loadURL('https://example.com');
    win.openDevTools();
});

Answer

openDevTools is basically a function of webContents (when used on BrowserWindow it’s only redirected)

So you can open devtools of main window with

win.webContents.openDevTools()

And for the BrowserView with

view.webContents.openDevTools()
