Equivalent node:crypto commands for CryptoJS (to migrate after deprecation)

We are using CryptoJS in our code but now that 4.2.0 comes with a big deprecation notice we plan on moving off. We'd like to eliminate the CryptoJS lib completely, and just use node:crypto going forward, but I can't figure out the proper incantation of node:crypto commands to decrypt something that was encrypted with CryptoJS:

// Current encryption method
// `secret` is a 64 byte string
CryptoJS.AES.encrypt(text, secret).toString() // => base64 string

// Current decryption method
// `encText` is the base64 string derived from above
CryptoJS.AES.decrypt(encText, secret).toString(CryptoJS.enc.Utf8)

We'd like to be able to decrypt using node:crypto and then re-encrypt using a more secure version, with an iv and all that good stuff. I've tried several different iterations of this code, with 6 different algorithms, but none of them are able to decrypt:

// Proposed decryption method for existing CryptoJS-encrypted text
// `algorithm` is one of aes128 | aes192 | aes256 | aes-128-cbc | aes-192-cbc | aes-256-cbc
// `secret` is same 64 byte string used to encrypt
// `encText` is the base64 string from `CryptoJS.AES.encrypt()`

const decipher = crypto.createDecipher(algorithm, secret);
let decryptedText = decipher.update(encText, "base64", "utf-8")
decryptedText += decipher.final("utf-8")

The node:crypto docs state:

The implementation of crypto.createDecipher() derives keys using the OpenSSL function EVP_BytesToKey with the digest algorithm set to MD5, one iteration, and no salt.

Which sounds similar to what CryptoJS is doing, but maybe not similar enough. :(

I've tried truncating the secret to only 32 characters (tried both first 32 and last 32) but it didn't help.

Any ideas of what else I could try? For testing, here's the encText and secret that should decrypt to Hello, world:

const CryptoJS = require('crypto-js')

const encText = 'U2FsdGVkX18ZLpNMrgcEPbbEfE2c6h3E9kc0GRLE4pU='
const secret = 'V7gRKWw4uz6QVH7cGHqcUEPHpr8CfqD4LTckiTpmdeeDzS423Zc7zaBngvpwBv6Y'

CryptoJS.AES.decrypt(encText.secret).toString(CryptoJS.enc.Utf8) // => 'Hello, world'
