i don't understand why requests are failing.

i don't understand why requests are failing.
i have free plan, i can normally use github copilot in browser, in vs code, and i succesfully logged into github copilot app. when i try to send a message "hello", it responds:
"you are not authorize to use this copilot feature, it requires an enterprise or organization policy to be enabled" ?

Start by reproducing the request from the /chat path in GitHub Copilot app version 1.1.12 on Windows 10 with the reported free-plan account. Compare the result with access in the browser and VS Code; done means determining whether the authorization message is expected or indicates an app defect, then documenting the finding.
