Error loading external URL in Electron.js application

Question

I am using Electron.js to load an external url. In this case, the whatsapp web. However, the following error is occurring: "O Whatsapp funciona com Google Chrome 49 ou superior".

I already changed Useragent however, the error continues.

wpp.loadURL('https://web.whatsapp.com/', {
       userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36'
      });
