[Bug]: AxiosError: Request failed with status code 403

Description

Hi,

I have managed to build and run the sample (see screenshot). However, as you can see, I am not getting any results, only a server error (this is from the VS Code terminal on Mac OS). My app gets created in the developer portal, but just to confirm — I intentionally did not log in to my Azure account as I am trying this out locally. I have logged into my production M365 account, and custom app sharing is enabled. Also, I have a Copilot license. I must be missing something. Please see the screenshot. In the "developer info" section, the plugin did get called but doesn't provide any further debug messages.

Azure OpenAI was enabled for Managed Identity only. Once I enabled API access all is working.
