### Checklist - [X] I agree to the terms within the [OpenFGA Code of Conduct](https://github.com/openfga/.github/blob/main/CODE_OF_CONDUCT.md). ### Describe the problem you'd like to have solved As a user, I'd like to be able to get the response headers when using `OpenFgaClient` ### Describe the ideal solution `OpenFgaClient` will have `get_headers()` and `get_raw_response()` methods that allow users to retrieve the headers and raw response respectively. Batch Methods such as non transactional write and batch check would have these methods on individual responses. ### Alternatives and current workarounds _No response_ ### References _No response_ ### Additional context _No response_
