Nodejs Kiteconnect Client and Websocket Not working

I am unable to get Nodejs Kiteconnect client and Websocket running.

import { KiteTicker } from 'kiteconnect';
import { KiteConnect } from 'kiteconnect';

const requestToken = ' '
const apiSecret = '';
const apiKey = '';
const accessToken

let kc = new KiteConnect({
	api_key: apiKey
});

kc.generateSession(requestToken, apiSecret).then(session => {
    access_token = session.access_token;
    
  }).catch(err => {
    console.log(err)
  });


let ticker = new KiteTicker({
	api_key: apiKey,
	access_token: accessToken
});

ticker.autoReconnect(true, 10, 5);
ticker.connect();
ticker.on("ticks", onTicks);
ticker.on("connect", subscribe);

function onTicks(ticks) {
	console.log("Ticks", ticks);
}

function subscribe() {
	var items = [738561];
	ticker.subscribe(items);
	ticker.setMode(ticker.modeFull, items);
}

import { KiteTicker } from 'kiteconnect';
       ^

The getting started with API Code Documentation on the Github Nodejs Client doesn't work as well, I have tried getting that to work.
In my attempts at getting it to run, I have -
Changed Node Versions from latest v.14 to previous versions
Added a declaration d.ts file stating Kiteconnect to be a module

Still I am unable to even get the it running


Please do give suggestions on how to sort this out
