How would I make an acronym possessive? I've tried using \gls{ACR}['s] but that will just print out "Acronym (ACR)'s".
main.tex is typed as follows:
\documentclass{article}
\usepackage[acronym]{glossaries}
\makeglossaries
% acronyms:
\newacronym{ACR}{ACR}{Acronym }
\begin{document}
\gls{ACR}['s]
\end{document}
