Electron AutoUpdater Issue

I have an issue with updating Electron app from a private repo. I'm using https://github.com/electron-react-boilerplate/electron-react-boilerplate for web.

I've tried Hazel + Vercel approach(https://github.com/vercel/hazel) but i receive Cannot find Squirrel error.

I have target nsis and still getting Squirrel error.

   "win": {
      "icon": "./assets/android-chrome-512x512.png",
      "target": [
        "nsis"
      ]
    },

What is the best way of doing autoupdates with private repo so it could scale and minimize bandwidth?

I'm asking because Hazel, Nuts and Nucleus are not maintained anymore and i'm having some hard time with Hazel.
