TypeError: FacebookConversionAPI is not a constructor

Description

When using package in an ES module, I get the following error:
TypeError: FacebookConversionAPI is not a constructor

When not using in an module, wit.h const instead of import, then the code works as expected.

Expected

No error when using ES import syntax 😄

Code

import http from 'http';
import FacebookConversionAPI from '@rivercode/facebook-conversion-api';

const FBConversionAPI = new FacebookConversionAPI(xxxxx);

const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

Versions

Node.js v17.8.0
FacebookConversionAPI v1.1.8
