CCA02M2 Quick Start Mics not Recognized

Hello I am working on a group project in which we have a Nucleo-H723ZG and a CCA02M2 expansion board. We attempted to follow this quick start guide: https://www.st.com/resource/en/product_presentation/x-nucleo-cca02m2_quick_start_guide.pdf 

However, at step 8 we cannot get the expansion board to be recognized as a microphone device on our computer. We do have a different Nucleo board than the guide, but not know what is going wrong.
