how to debug "Failed to authenticate with copilot"

Hi, 

I'm using corporation github copilot license and the copilot.vim plugin was authenticated and works fine, but CopilotChat can't work due to the error message:

```
WARN ...  /<home>/.local/share/nvim/lazy/CopilotChat.nvim/lua/CopilotChat/client.lua:396: Failed to authenticate with copilot: ...zy/CopilotChat.nvim/lua/CopilotChat/config/providers.lua:130: {}
```

How do fix this issue? Thanks
