[Tex/LaTex] Natbib shows reference style without square brackets

Question

I'm trying to get natbib to display the \bibliographystyle{aaai-named} as this documents shows.

But when I try, I do not get that result there are no square brackets around the author name and author year.

My code:

\documentclass[english, oneside, 12pt]{memoir}

\usepackage[square, authoryear]{natbib}

\begin{document}
\citep{agrawal2014development}

\bibliographystyle{aaai-named}
\bibliography{References}
\end{document}

References.bib:

@article{agrawal2014development,
    title={Development and Comparison of Open Source based Web GIS Frameworks on WAMP and Apache Tomcat Web Servers},
    author={Agrawal, Sonam and Gupta, Rajan Dev},
    journal={Proceedings International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences},
    volume={4},
    pages={1--5},
    year={2014}
}

Edit 1:
Minimal example was written wrong. It is now updated.

Answer 1

Without natbib and using apalike:

MWE:

\documentclass[english, oneside, 12pt]{book}

\begin{document}
\cite{agrawal2014development}

\bibliographystyle{apalike}
\bibliography{References}
\end{document}
