including CCS concepts and keywords

https://sci-k.github.io/2023/#submission asks "Please remember to add Concepts and Keywords". I think that "Concepts" refers to ACM Computing Classification System. The Overleaf template https://www.overleaf.com/latex/templates/association-for-computing-machinery-acm-sig-proceedings-template/bmvfhcdnxfty shows this code for CCS classes and keywords:

%% The code below is generated by the tool at http://dl.acm.org/ccs.cfm.
%% Please copy and paste the code instead of the example below.
\begin{CCSXML}

\ccsdesc[500]{Computer systems organization~Embedded systems}
\ccsdesc[300]{Computer systems organization~Redundancy}
\ccsdesc{Computer systems organization~Robotics}
\ccsdesc[100]{Networks~Network reliability}

%% Keywords. The author(s) should pick words that accurately describe
%% the work being presented. Separate the keywords with commas.
\keywords{datasets, neural networks, gaze detection, text tagging}

I started posting this issue, but then I saw the respective code in https://github.com/quarto-journals/acm/blob/main/template.qmd#L107 . I still decided to post the issue as a reference (and maybe you can add instructions to the README?)

Notes:

The tool http://dl.acm.org/ccs.cfm generates such markup
500 is high significance (relevance), 100 (or missing number) is low significance
