Any example about customing the low-level library of Gst-nvtracker?

I am a fresher in deepstream. Now I can find the introducation about the nvtracker element Gst-nvtracker — DeepStream 6.1.1 Release documentation. and I want to define the custom algorithm like deepsort and so on. My question is are there any examples to show how to use the lowlevel library rather than just tell you some annotation?

No. There is no sample. The API description is Gst-nvtracker — DeepStream 6.1.1 Release documentation
