How to parse IMU value of Oculus Quest 2?

Hi I'm doing a robot making contest and needs IMU value(espically yaw rotation) to deploy my camera video to my Oculus Quest 2. I download the C++ SDK for Quest 2.

My develope environments are like below
Use C++ and OpenCV 4.7.0

Qt Creator(Qt 6.4.2)

MinGW 11.2.0

Windows 11

How can I get imu value from Oculus Quest 2 using SDK? I'm quite a beginner of C++ and I looked the C++ SDK codes, but I cannot get where to start.
