Good afternoon and thank you for your question!
Can I please know if you wanted to:
- Get all messages from all chats that a user is a participant in, including one-on-one chats, group chats, and meeting chats.
- Retrieve a single chat (without its messages)?
- Retrieve a single message or a message reply in a channel or a chat.
Please let me know what will be your goal so that I can assist you further. Have a great day ahead! 😊
