Can't perform authentication with guess-ga

1. I created a project in google console.
2. I created a private key with no restrictions
3. I opened a google analytics account
4. I added analytics.js and used angulartics2 for Angular (and the routes recordings worked)
5. Running :

  plugins: [
    new GuessPlugin({
      debug: true,
      GA: viewId,
      runtime: {
        delegate: false
      },
      routeProvider() {
        return parseRoutes('.');
      }
    })
  ]
};

Can't seem to pass this code in main.js:

 client = google_oauth2_node_1.auth({
                  clientId: clientId,
                  clientSecret: clientSecret,
                  scope: scope
              }).then(function (token) {

Opens a new chrome tab and clicking on my user get's me:

Sign in with Google temporarily disabled for this app This app has not been verified yet by Google in order to use Google Sign In.

Also when trying:

fetch({
  key,
  viewId,
  period: {
    startDate: new Date('2016-1-1'),
    endDate: new Date('2020-3-3')
  }
}).then(g => {
  writeFileSync('data.json', JSON.stringify(g, null, 2));
}).catch((err) => {
  console.log(err);
  throw err;
});

throws Login Required. I tried to give guess js read only permissions by email (mgechev@...) in google analytics but it didn't work.
