Asynchronous PDF Extract API calls using the Python SDK

We are working on a project that requires us to extract data from multiple PDF files for a user/session using the Python SDK. We want to speed up the process by making asynchronous (concurrent) Extract API calls using the asyncio and await functions. However, we are facing some issues with this approach. The Extract API calls are not running concurrently, but sequentially. We are wondering if there is a way to fix this problem or if there is a limitation of the Python SDK that prevents us from making concurrent Extract API calls.
