帮助重现带有装饰的 tcolorbox

Question

我正在尝试复制这个盒子，但菱形位于椭圆形盒子的右侧。

我不知道如何创建菱形以及如何以那种方式放置它。

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{tikz,tikzpagenodes}
\usepackage[most]{tcolorbox}
\usetikzlibrary{calc}
\usetikzlibrary{intersections, patterns}
\tcbuselibrary{skins}
\usepackage{lipsum}
\usepackage{xcolor,etoolbox}



\definecolor{boxcolor}{RGB}{50,232,250}

\newtcbox{\exobox}{on line,
arc=7pt,colback=white!10!white,colframe=boxcolor,
before upper={\rule[-3pt]{0pt}{10pt}},boxrule=2pt,
boxsep=0pt,left=12pt,right=12pt,top=2pt,bottom=2pt}


\begin{document}
\exobox{ See exercise 3}

\end{document}

您可以使用该形状diamond绘制菱形并将overlay其添加到您的tcolorbox。

感谢 Ignasi 指出菱形应该位于右侧。

我已经创建了一些替代方案，请选择您喜欢的那个。
