Where are the classes for yolox_s_inf_decorder.onnx

[kairibu]

Hi all,
I am following this tutorial to get pre-trained yolox_s running: https://docs.opencv.org/4.x/da/d9d/tutorial_dnn_yolo.html

Its working fine so far, however I don't understand where I can find the classes file?
I think it should be a text file with one class per line.

Any hint is much appreciated,

thx
