How to assign author variables from the YAML header to LaTeX code in journal template

Description

I have this little Quarto project to build a journal submission template for the American Political Science Review (APSR).

Here is the repo.

One thing I need to do is to figure out how to convert the names and affiliations of authors in the YAML header into variables in the LaTeX code. Here is what the official journal template LaTeX code looks like:

% The custom \author command takes THREE arguments:
% #1 = Author name
% #2 = Affiliation name
% #3 = Brief author profile, or anything that you'd usually put in a \thanks. Leave blank {} if there's nothing to be said.
\author{Author One}
       {Affiliation A}
       {Author One is PhD Candidate, ABC Department, Affiliation A, 12345 NY. ([email protected])}
       
\author{Author Two}
       {Affiliation C}
       {Author Two is Assistant Professor, Faculty of Z, Affiliation B, 42813. Corresponding Author ([email protected]) Additional notes about Author Two.}
       
\author{Author Three}
       {Affiliation B}
       {Author Three is ...}

And here is what I want to build for the YAML header:

author: 
  - name:
    affiliation:
    profile:
  - name:
    affiliation:
    profile:
  - name:
    affiliation:
    profile:
``

I understand how to have one YAML parameter reflected in the LaTeX code, e.g. `\title{$title$}` but I am stumped by the "stacking" of parameters in one field like this. 

Is there some documentation or tutorial I can read to get a handle on how to do this?
