How to see Codex final message to openai?

[RoySadaka]

When looking at .codex/sessions files, i see that instructions such as:
"# Collaboration Mode: Default\n\nYou are now in Default mode. Any previous instructions for other modes (e.g. Plan mode) are no longer active.\n\nYour active mode changes only when new developer...."

Is there a way or a tool to see the actual input (system message, user message, and rolling conversation) in a convenient way? i mean literally what is being sent to OpenAI servers?
