AWS connect documentation change

Service: connect · 2026-01-25 · Documentation medium

File: connect/latest/adminguide/message-streaming-ai-chat.md

Summary

Added detailed instructions for enabling message streaming via API/console, updated Lex bot permissions to include lex:StartConversation, and added configuration notes.

Security assessment

While the changes involve permission updates (adding lex:StartConversation), this appears to be a feature enhancement rather than addressing a security vulnerability. The documentation explains how to enable a functionality but doesn't introduce new security controls or address known security issues.
