Support Codex Remote control from desktop and Linux apps

Feature request

Please add Codex Remote host selection and remote task control to the ChatGPT/Codex desktop app, including Linux.

Use case

I use a Steam Deck as a portable development device and want it to act as a control plane for Codex running on another computer. Today, the documented Remote experience is centered on mobile, which leaves desktop-class portable Linux devices without a native way to control a connected Codex host.

Desired capabilities

• Select a connected host and workspace from the desktop/Linux app
• Start and steer remote tasks
• Respond to approval requests
• Review diffs and task results
• Manage multiple connected machines
• Preserve the security and host-boundary model of the existing Remote experience

Why this matters

A native desktop/Linux Remote client would be more reliable and accessible than running an emulated mobile app or a full remote-desktop session. It would also make devices such as the Steam Deck useful portable Codex control consoles without requiring the code to execute locally.

The issue does not name files, tests, or an entry point. Begin by locating the existing Remote experience and the desktop/Linux app entry point, then map host selection, task control, approvals, diffs, and multi-machine support. Done means desktop and Linux clients provide the requested Remote capabilities while preserving the existing security and host-boundary model.
