Using Meteor, how do requestPermissions for Google Calendar with loginWithGoogle (without accounts-ui package)?

Question

I am building a Meteor application that requires access to a logged in user's Google Calendar account.

Currently I have Google Sign in on my login form (along with native account login) working. A user can sign in successfully using their Google Account.

I achieved the above as follows:

I installed the accounts-google and service-configuration packages. I already had the accounts-password package installed.

Next, I created a file in /server/lib/config called accounts.js that contains the following:

 Meteor.startup(function () {
  // Add Google configuration entry
  ServiceConfiguration.configurations.update(
    {service: "google"},
    {
      $set: {
        clientId: "*****.apps.googleusercontent.com",
        loginStyle: "popup",
        secret: "*****"
      }
    },
    {upsert: true}
  );
});

This allows a user to click on the Sign in with Google button, which renders a popup and allows them to sign in. Afterwards they are redirected to my app.

Now for (first) my question: how can I requestPermissions (as mentioned here in the official Accounts Docs) to access a user's Google Calendar? More specifically, where can I access the Accounts.LoginWithGoogle() method?

I have looked at other SO questions (such as this) explaining how to do it. However, they all use the accounts-ui package.

Also, how can I use the Google OAuth token I get from authentication offline (say, pass it to a Python script or having access to it via a MongoDB call)?

Any help would be greatly appreciated.

You can pass the same options as in the question you linked to to the Meteor.loginWithGoogle method.

Specifically, refer to this docs page: docs
