Advice adding support for the latest version of reminders

The problem

I'm trying to add support for the latest version of reminders and I've gotten stuck at trying to figure out how to decrypt the text I'm getting back from https://p53-ckdatabasews.icloud.com/database/1/com.apple.reminders/production/private/records/query .

I'm assuming the data I want is in the key TitleDocument, it's value is encrypted and the type is 'ENCRYPTED_BYTES'.

Anyone have experience with these encrypted values? Have you seen this in other iCloud services? Any advice would be much appreciated. Thank you.

Environment

• pyiCloud release with the issue (pip show pyicloud): local clone of the master branch
• Last working pyiCloud release (if known):
• Service causing this issue: reminders
• Python version (python -V): 3.9.12
• Operating environment (project deps/Docker/Windows/etc.): Pop!_OS

Traceback/Error logs

Checklist

• [x] I've looked informations into the README.
• [x] I've looked informations into the pyiCloud's code.
• [x] I've looked informations in Google.

Additional information

The values returned with the type ENCRYPTED_BYTES appear to be using Base64, which can be decoded using Python's standard base64 module. Have not attempted to implement it in this codebase, but worth testing. The decoding returns a byte object by default, so it must be converted to a string.

import base64

base64.b64decode(<VALUE_VARIABLE>).decode("utf-8")

@ssennettau I agree, many of them are, especially in Notes, but in Reminders they appear to be more encrypted or another encoding.

My 5 cents here, we can try to inspect js code from https://icloud.com, i have tried, but without success. Here is TitleDocument decodes, 0.main.js, find by keywords.
