How to use deepsort reidentification in deepstream?

Can you share any references to do it?
My target: Face reidentification from video using deepsort.

Please refer here for NvDeepSORT tracker :Gst-nvtracker — DeepStream documentation 6.4 documentation

Shall I use : embedder (deep_sort_real_time)
some references please

Here is the DeepStream samples: C/C++ Sample Apps Source Details — DeepStream documentation 6.4 documentation (nvidia.com)
You can use apps/sample_apps/deepstream-test2 which include nvtracker.
Or are you just want Re-ID model as SGIE in your pipeline?
