索引中的子条目带有 acro/imakeidx

Question

我缺少一些关于如何在生成的索引中输入子条目的信息acro/imakeidx。

assetclass不被理解为 的子条目asset。

\documentclass{book}
\usepackage{acro}
\usepackage{imakeidx}
\makeindex

\acsetup{
    index/use=true
}

\DeclareAcronym{asset}{%
    short=asset, 
    long= underlying asset
}

\DeclareAcronym{assetclass}{%
    short=asset class, 
    long=asset class, 
%    index = {\ac{asset}!class}
    index = {asset!class}    
}

\begin{document}

This is the demonstration of the usage of \ac{asset}---which is not to be confused with \ac{assetclass}.

\printacronyms

\printindex

\end{document}

仅供记录，@Cicada 的评论回答了我的问题。

\documentclass{book} 

\usepackage{acro} 
\usepackage{xcolor} 
\usepackage{imakeidx} 
\makeindex[columns  = 1]

\acsetup{ index/use=true } 

\DeclareAcronym{asset}{% 
    short=asset, 
    long= underlying asset, 
    index={asset}, }

\DeclareAcronym{assetclass}{% 
    short=asset class, 
    long=asset class, 
    index = {asset!class} } 

\begin{document} 

This is the demonstration of the usage of \ac{asset}---which is not to be confused with \ac{assetclass}.

\printindex
