How to add publisher in electron builder

Question

I am new to electron and trying to add publisher in electron builder. But when it creates the installer it says publisher as unknown.

My build obj in package.json is

"build": {
    "appId": "app.name",
    "win": {
      "target": "nsis",
      "icon": "iconnewa1.ico"
    },
    "publish": {
      "provider": "s3",
      "bucket": "bucket_name"
    },
    "mac": {
      "category": "app.category",
      "target": [
        "zip",
        "dmg"
      ]
    },
    "nsis": {
      "perMachine": true
    }
  }

Please help me with this. I have search whole documentation to add publisher in electron builder but unable to get any success.

You must use Code Signing to avoid that:

The regular (and often cheaper) Code Signing Certificate shows a warning during installation that goes away once enough users installed your application and you've built up trust. The EV Certificate has more trust and thus works immediately without any warnings.
