Load chat sessions from the iMessage chat.db SQLite file.
It only works on macOS when you have iMessage enabled and have the chat.db file.
The chat.db file is likely located at ~/Library/Messages/chat.db. However, your
terminal may not have permission to access this file. To resolve this, you can
copy the file to a different location, change the permissions of the file, or
grant full disk access for your terminal emulator
in System Settings > Security and Privacy > Full Disk Access.
