Electron how to intercept http response body

Is there some way to intercept BrowserWindow http response body in main process without debugger?

Is it impossible to use WebRequest class and onCompleted method?

I can do that with debugger but for some reason I can not use this

await w.webContents.debugger.sendCommand('Network.enable')
  w.webContents.debugger.on('message', async (event, method, params) => {
    if (method === 'Network.dataReceived') {
      const responseBody = await w.webContents.debugger.sendCommand('Network.getResponseBody', {requestId: params.requestId})
    }
  })

UPD

I found only one solution expect debugger. It is not perfect but it solve my issue.

Use webPreference.preload to inject this monkey patching script.

let oldXHROpen = window.XMLHttpRequest.prototype.open;
window.XMLHttpRequest.prototype.open = function(method, url, async, user, password) {
 this.addEventListener('load', function() {
  console.log('data: ' + this.responseText);
 });

 return oldXHROpen.apply(this, arguments);
}

console.log may be replaced with ipc to send this data to main process
