The changes look good to me, I don't see the extra menu anymore on my end on macOS:

Proposed Changes
#4172 added an app menu (hamburger) button to the agentic UI sidebar so Windows and Linux users can reach the app menu — those platforms have no native menu bar in production. The button rendered unconditionally, so it also appeared on macOS, duplicating the native application menu (p1784109157531499/1784109157.531499-slack-C06DRMD6VPZ), and in the browser-hosted UI (
studio ui), where it did nothing.The connector now declares whether the host needs an in-UI app menu entry point, and the sidebar only shows the button when it does: Windows/Linux desktop keeps it, macOS and the browser don't.
