Electron updater not working

I have followed the following document to use `electron-updater` but it does not work.
https://www.electron.build/auto-update
https://gist.github.com/iffy/0ff845e8e3f59dbe7eaf2bf24443f104

I uploaded outcome of `yarn dist` which is a windows installer to firebase storage.
And set `package.json` like below but had no chance to make it work
```
"build": {
"publish": [
{
"provider": "generic",
"url": "https://MY_URL"
}
]
}
```

No repository file, test, or entry point is identified. Start by reviewing the linked electron-updater documentation and the package.json build.publish configuration, then compare the Firebase-hosted Windows installer with the configured generic URL; done means the updater detects and installs a newer release.
