i’m working with jmeter JSR223 postprocessors and i need help to convert a javascript code to Groovy, my Javascript code is:

// Lee el contenido de crypto-js.js desde el archivo descargado
load('C:/Users/hlopezgu/Desktop/cryptojs/node_modules/crypto-js/crypto-js.js');
load('C:/Users/hlopezgu/Desktop/cryptojs/node_modules/crypto-js/enc-utf8.js');

payload_response = vars.get("payload");
log.info("payload_response GET CONTACTS V1: " + payload_response);

// Función para desencriptar utilizando CryptoJS
function aesDecrypt(cipherAEStext, key) {
    var bytes = CryptoJS.AES.decrypt(cipherAEStext, key);
    var plaintext = bytes.toString(CryptoJS.enc.Utf8);
    return plaintext;
}

// Variables
var cipherText = payload_response;
var key = "6159ff99f26114c0c48ef1e1b1086f74b78b58572192c8d3a547ee9cde95557e";

// Desencriptar y almacenar en una nueva variable
var decryptedText = aesDecrypt(cipherText, key);
vars.put("decrypted_payload", decryptedText);

log.info("GET CONTACTS V1 Payload: " + decryptedText);

Thanks in advance
