Description

What issue are you seeing?

The Codex VS Code extension is installed and enabled, but the Codex chat panel/view is not showing.

I tried:

  • Opening Codex from the Command Palette
  • Developer: Reload Window
  • Checking the Activity Bar / secondary sidebar

None of these restored/opened the Codex chat UI.

Environment
  • Platform: macOS (Apple Silicon)
  • IDE: VS Code
  • Extension: openai.chatgpt
  • Extension version: 26.901.22334
  • Extension was updated on 2026-09-08
  • Extension page shows it as installed/enabled
Expected behavior

The Codex chat panel should be available/openable from VS Code after the extension is installed and enabled.

Actual behavior

The extension is present and enabled, but the Codex chat panel/view does not appear or open.

Additional information

This was observed immediately after/around the latest extension update. A screenshot is available showing the installed extension and version.

Research direction

Start by reproducing the missing Codex chat panel on macOS Apple Silicon with VS Code and extension version 26.901.22334, then check the Command Palette, Activity Bar, and secondary sidebar behavior. Done means the installed and enabled extension makes the Codex chat panel available and openable; no source file or test is named in the report.
