I am working on a project that needs to use a custom function in this function I need to use an npm package is that possible.

This is my code:

import numberToWords from "number-to-words";

export function TA(first1) {
console.log(first1);

// Convert the number to words
const words = numberToWords.toWords(first1);

return first1;
}

CustomFunctions.associate("TA", TA);

{

"functions": [
    {
        "description": "Add two numbers",
        "id": "TA",
        "name": "TA",
        "parameters": [
            {
                "name": "first1",
