LaTeX xsim: printing only even/odd number answer

Question

I am writing exercises sheets for my student and I want to print only solutions to odd (or even) numbered exercises using LaTeX xsim. I have searched on Google and looked in the xsim manual, but couldn't find anything. So is there an easy way to print only odd numbered solutions with xsim?

Thanks and have a great day Nicolas Leduc

Just an attempt:

\documentclass{article}
\usepackage{xsim}

\xsimsetup{
  exercise/within=section,
}

\begin{document}
\section{title}
\begin{exercise}
  first exercise
\end{exercise}
\begin{solution}
  first solution
\end{solution}

\begin{exercise}
  second exercise
\end{exercise}
\begin{solution}
  second solution
\end{solution}

\begin{exercise}
  third exercise
\end{exercise}
\begin{solution}
  third solution
\end{solution}

\section{title}
\begin{exercise}
  first exercise
\end{exercise}
\begin{solution}
  first solution
\end{solution}

\begin{exercise}
  second exercise
\end{exercise}
\begin{solution}
  second solution
\end{solution}

\begin{exercise}
  third exercise
\end{exercise}
\begin{solution}
  third solution
\end{solution}

\ForEachUsedExerciseByID{%
  \ifodd\GetExerciseProperty{counter-value}\relax
    \XSIMprint{solution}{#1}{#2}%
  \fi
}
\end{document}
