Missing create branch option in iOS Codex UI

In the iOS ChatGPT app, the Codex UI does not appear to show an option to create a new branch for a repository task.

This blocks the mobile workflow because users cannot easily start a Codex task that needs repository changes and a later pull request.

Expected behavior:

• Show a visible Create Branch option in the iOS Codex UI.
• Or show a clear message if this workflow is not supported on mobile.

Actual behavior:

• I cannot find the Create Branch option in the current iOS mobile UI.

Environment:

• ChatGPT iOS app
• Codex GitHub workflow
• Latest app version available when reported
