Reading video from OpenMV H7 camera over ttyACM0 port using c++ code

Question

I have an OpenMV H7 camera who's output I need to read into OpenCV. Now, the serial output is ttyACM0 where I am able to stream image frames. How can I read these frames in c++ code? I cannot use cv::VideoCapture() as the camera is not recognized as a video device. Serial libraries for C++ that I've found so far are quite messy. I am able to do this on python using serial library. Any help in reading into c++ would be valuable.
