如何将索引条目显示在与被索引的文本相同的行上

Question

是否可以将showidx索引条目显示在与被索引文本相同的行上？似乎不行，正如makeindx.pdf所说：

这个宏实际上排版盒子包含当前页面上的所有索引条目[...]。

这有点讽刺，因为，就makeindx.pdf其本身而言，由此描述的宏的名称\@mkidx位于边缘，就在文本的前面。（当然，环境似乎不同，\@mkidx可能不是索引条目。另一方面，cleveref.pdf也有边缘条目的文本似乎只是...文本。）

因此，鉴于我已经在使用hyperref和cleveref，tcolorbox答案可能是什么？希望答案不需要其他包裹。

这是一个相当长但最简单的例子：

% !TEX TS-program = pdflatexmk  
\documentclass{book}

    \usepackage{makeidx}
    \usepackage[hyperfootnotes=false]{hyperref}%[pdfborder={0 0 0}]
