Decrypting xChat

Hey guys, I have a AI chatbot on X that reads messages and sends messages through X API endpoints, using cookie of the account. Problem I'm facing is with the new Xchat update, all of the messages are encrypted, we've figured out how to decrypt small ones and how to send messages, but still can't figure out how to decrypt long messages.

Has anyone been able to fully decrypt it?

I'd appreciate any help!

A guy on twitter had his startup shutdown by elon for basically being too good of a tool, so he decrypted the chat lol, they released a monster:
