How to connect to Google Calendar API using service account using Node.js?

Question

How to use GoogleAuth client when using Node.js. I've looked up many articles and the client URL will provide a code data that I can use to get the client details. However, how can I use a service client to automatically authenticate on behalf of the client. I mainly need to get the GoogleMeet link and add it to the client's Google Calendar. I'm following this code. But this is manual URL authentication. https://github.com/isuruhettiarachchi/ssd-oa

Try something like the following, making sure domain-wide delegation is configured from your workspace account to the service account.

subject is the user on the 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!");
  }
});
