I'm testing out EAP Engagement Reporting and noticed no matter how many message I send as the agent from the interface through Messaging (and I went back and forth between the agent and diner for a while), both agent_message_count and agent_replies_count are always 0 in the response I get back both on the list engagements API and get engagement by ID.
While we're at it, can you please explain what is the difference between agent_message_count and agent_replies_count?
