codex - 💡(How to fix) Fix Computer Use Chrome extension is unavailable in Chrome Web Store; is there an offline installer?

What happened

The Chrome extension used by Codex Desktop's Computer Use / Google Chrome integration cannot currently be downloaded from the Chrome Web Store.

The Chrome Web Store page opens at:

https://chromewebstore.google.com/detail/hehggadaopoacecdllhhajmbjkdcmjag/error

but it shows an error page saying the item cannot be purchased or downloaded. In my localized Chrome UI, the message is:

此商品无法购买或下载

In Codex Desktop settings, the Computer Use > Google Chrome page still shows Chrome as not connected and offers "Reinstall extension", but following the store link leads back to the unavailable item page.

Environment

• OS: Windows
• Codex desktop app package: Microsoft Store / WindowsApps
• Appx package observed locally: OpenAI.Codex_26.506.2212.0_x64__2p2nqsd0c76g0
• Area: Settings > Computer Use > Google Chrome
• Chrome Web Store extension ID from the failing URL: hehggadaopoacecdllhhajmbjkdcmjag

Expected behavior

The Chrome extension needed for Computer Use should be installable from the Chrome Web Store, or Codex should provide a documented fallback installation path.

Actual behavior

The Chrome Web Store reports that the item cannot be purchased or downloaded, so the Computer Use Google Chrome integration cannot be connected through the in-app install/reinstall flow.

Question / request

Is there an official offline installer, CRX package, unpacked extension bundle, or another documented fallback that users can download and install manually when the Chrome Web Store page is unavailable in their region/account/browser?

If an offline package is not currently available, could one be provided or documented for cases where Chrome Web Store distribution is blocked or unavailable?
