Xcode 26 | Coding Intelligence: Signing into ChatGPT Enterprise account yields error message

Hello,

When trying to login into my ChatGPT Enterprise account within Xcode 26 to setup Coding Intelligence, after credentials and OTP have been accepted, I'm getting the following error message from ChatGPT/OpenAI:

Route Error (400 ): {
    "error": {
        "message": "No eligible ChatGPT workspaces found.",
        "type": "invalid_request_error",
        "param": null,
        "code": "chatgpt_account_missing"
    }
}

What am I missing here?

Any help is highly appreciated. Thank you!
