How to call External Javascript Firestore function in a Typescript file?

Question

I am using Node.js to upload a Typescript file(index.ts) with Cloud functions. I now have a Firestore trigger written in external JavaScript file(notifyNewMessage.js), which I would like to somehow declare in the Typescript file.

Both files are in the same directory:

index.ts:

import * as functions from 'firebase-functions'
import * as admin from 'firebase-admin'

//declare javascript file here???

export const cloudFunction= functions
  .firestore.document(`Users/{user_id}`).onWrite(async (change, _context) => {

   //Function code....

}

notifyNewMessage.js

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();

exports.notifyNewMessage = functions.firestore{
   //Cloud function I want to declare in index.ts
}

It would be great if anyone can provide a way for me to do this, or point me in a direction where I can learn how, as Typescript and JavaScript are not my strong points :)

Thanks in advance!

Assuming you are trying to import an exported function from the js file. Wouldn't it be something simple as one of the following:

import notifyNewMessage from "./notifyNewMessage";

OR

import { notifyNewMessage } from "./notifyNewMessage";
