Rather than some random github, have you tried googles own documentation? — Jaromanda X, Aug 17 '23 at 06:48
Does this answer your question? [Is there is a way to grant my nodejs application access to my google calendar?](https://stackoverflow.com/questions/60929631/is-there-is-a-way-to-grant-my-nodejs-application-access-to-my-google-calendar) — Linda Lawton - DaImTo, Aug 17 '23 at 07:23
Check out Aurinko API. You can upload your service account key and then create 'managed accounts' that represent users using the service account: https://apirefs.aurinko.io/#tag/Managed-accounts/operation/upsertManagedAccount — Alexey, Aug 18 '23 at 12:44

Try something like this make sure to configure domain wide delegation to the service account from your workspace account.

subject is the user on your domain you want the service account to impersonate.

let google = require('googleapis');
let privateKey = require("./privatekey.json");

var jwtClient = new google.auth.JWT({
       email: privateKey.client_email,
       key: privateKey.private_key,
       scopes: ['https://www.googleapis.com/auth/calendar'],
       subject: 'user@domain.com'
    });

jwtClient.authorize(function (error, tokens) {
  if (error) {
    console.log(error);
    return;
  } 
  else {
    console.log("Successfully connected!");
  }
});

how can i use it to create event for individuals of other domain. — Sruthi, Aug 17 '23 at 08:52
You need the admin of that domain to configure domain wide delegation for your service account. This will allow you to then access the users within that domain. — Linda Lawton - DaImTo, Aug 17 '23 at 11:46
