Electron Angular how to use localstorage

I downloaded this project

I'm using the electron-store module to store data but I don’t know how to import it within the angular project. The module works in them in the electron's main.ts.

So I tried the following:

export class HomeComponent implements OnInit {
  constructor(private router: Router, private store: store) {
    console.log(store.get('unicorns'));
  }
}

But I always got null when testing it.
I’m sure I did something wrong. Can someone help me with this problem?
