Chat Module | Update Feature

User Story

As a user, you should be able to edit or modify your sent chat with a valid message ID and user ID. First, the system will check if there is a chat with this ID in the database and whether the message is associated with this user ID or not. If the message ID is invalid, the error message will be "Invalid message ID details." If the user ID is not associated with this message ID, the error message will be "Invalid user ID for the chat." If the chat and message IDs are valid and associated with the user, the system will update the message. Otherwise, it will throw an "Invalid chat update details" error.
