LaTeX not generating header

Question

Brand new to LaTeX. I wanted to start simple by generating a one-page research statement following this minimalist research statement template on Overleaf. In the example, it clearly shows a running head including the author name and title in the upper right and left corners, respectively.

Unfortunately, when I open the template those components are missing and I cannot figure out how to correct what's already here to fix it.

This is the main .tex document, in which I've tried to replace YourName and Statement Type with my details:

.tex Document:

% 
% This format is intended to be used for frequently requested
% academic statements, like research and teaching statements.
%
% Uses Atkinson Hyperlegible font for better accessibility
%        (see https://brailleinstitute.org/freefont)

\documentclass[12pt]{ministate}
\name{YourName}
\statement{Statement Type}
\begin{document}
\runninghead
\thispagestyle{fancy}
Sample text about how cool you are at doing stuff.
Some more sample text.
\textbf{A bold statement about you}, and how good your work is.
\bibliographystyle{plain}
\end{document}

This uses the Arkinson Hyperlegible font and references a .cls file which I'll append to the bottom here.

Troubleshooting:

I've reviewd the fancyhdr documentation but haven't been able to figure out from that what is being misused. While I'm a proficient coder in some other langauges (Python, R, Bash, etc.), I'm still getting my bearings for how functions are defined in LaTeX and I'm wondering if that's where teh issue lies here. I did try to skip functions entirely and just directly specify the text I want in the header in the .cls document where the \@function_name are placed in the header function, but that did not work either.

I'm sure I'll figure it out as I learn more LaTeX but figured I'd see if the community could steer me in the right direction. Regardless, thanks so much for your time!

Answer 1

I will post the initial version that addresses the issue. The solution might not be optimal, and I encourage the community to improve it further.

% The package requires XeLaTeX to compile because of the custom fonts.
