List of todos (todonotes) is empty with acl2020

Question

The todonotes list of todos appears empty when using the acl2020 style package (available here).

Here's a working example:

\documentclass[11pt,a4paper]{article} %list of todos is empty
\usepackage[hyperref]{acl2020}
\usepackage{todonotes}

\begin{document}

\listoftodos

\section{Contents}
test text \todo{test}

\end{document}

There's a similar question with the llncs document style, however the fix, \setcounter{tocdepth}{1} doesn't help.

Answer 1

The ACL style contains the following:

% We're never going to need a table of contents, so just flush it to
% save space --- suggested by drstrip@sandia-2
\def\addcontentsline#1#2#3{}

You can edit the style to only flush the TOC lines for the final copy:

% We're never going to need a table of contents, so just flush it to
% save space --- suggested by drstrip@sandia-2
\ifacl@finalcopy
\def\addcontentsline#1#2#3{}
\fi
