Hi,

I'm using openai-python library v1.3.5 with the AsyncAzureOpenAI client.

I'd like to get the rate limiting information in the response headers, see this issue for more context: https://github.com/openai/openai-python/issues/416#issuecomment-1795428669

But the response headers do not seem to contain this information when using Azure OpenAI.

Does the Azure OpenAI API returns this information? If yes, how to retrieve the information?

Thanks
