Is OpenCV's stitching class using the function "findHomogragy" or any other function? I can't find it in the stitching class.

In this documentation page you can find everything about the Stitching class:

Take a look at the Stitching pipeline to have an idea of the whole process

I can't find the homography in the code and provided pipeline there. Can you please help with a little hint?

I don't really know what you're exactly expecting to find, the Stitching class is complex and there's not a single homography function that solves the whole problem. As you can see, features are found and matched, and then it estimates cameras parameters and rotations (you can see there's a detail::HomographyBasedEstimator function, if that is what you're looking for...). If you want to know more, I'd recommend you to read the paper used to implement the pipeline (as stated in the docs, it's M .Brown and D. Lowe. Automatic Panoramic Image Stitching using Invariant Features. International Journal of Computer Vision, 74(1), pages 59-73, 200)
