How can I use natbib citation style in a specific template?

Question

I'm working with the NeurIPS template on overleaf. From my reading, I understand that natbib is the default package for reference. I tried to read the instruction carefully and also read the official Overleaf's tutorial on natbib.

But I still can't use the reference normally? I prefer to have references in a separate file, e.g, my_ref.bib that contains:

@inproceedings{Arora2018StrongerGB,
  title={Stronger generalization bounds for deep nets via a compression approach},
  author={Sanjeev Arora and Rong Ge and Behnam Neyshabur and Yi Zhang},
  booktitle={International Conference on Machine Learning},
  year={2018}
}

and then in main.tex, I do this:

\section*{References}
\bibliographystyle{IEEEtran}
\bibliography{my_ref}

[Edited] I added the IEEEtran.bst file.

and then use \cite{Arora2018StrongerGB} in the main.tex. I also tried citet{Arora2018StrongerGB}. But it also doesn't work with this template.

Feel free to inspect the project: https://www.overleaf.com/8778352361kqjtqqkyncyw

Any recommendation is appreciated. Thanks!
