[ACTION] Slack "list_replies" tool MCP needs to be improved

Using my AI app to get Slack user's response always fails.

The tool **list_replies** requires a timestamp to fetch message responses, but this isn't possible (to determine the timestamp) when an external app connects via MCP. Therefore, we need a tool to retrieve replies from a specific Slack channel without relying on the timestamp or use additional code to parse the list within a loop.
