So erstellen Sie Fancybox mit Tcolorbox

Question

Ich möchte eine schicke Box wie die unten erstellen. Bisher ist es mir jedoch gelungen, das folgende Bild zu erstellen, das eigentlich nicht das ist, was ich brauche. MWE

\documentclass{article} 
\usepackage[many]{tcolorbox} 
\tcbuselibrary{skins} 
\newtcolorbox[auto counter,number within=section]{myex}[1][]{ 
before=\bigskip\centering,
after=\bigskip,
breakable, 
enhanced, 
arc=15pt, 
colback=white, 
fonttitle=\sffamily\bfseries,
title=Ex~\thetcbcounter,
frame hidden, 
sharp corners, 
rounded corners=southeast, 
attach boxed title to top left, 
boxed title style={ 
 enhanced, 
 colframe=purple!65!blue, 
 colback=purple!65!blue, 
 arc=5pt, 
 borderline east={2pt}{6pt}{white}, 
 borderline east={2pt}{2pt}{white}, 
 bottomrule=0pt, 
 rightrule=0pt, 
 sharp corners, 
}, 
interior style={}, 
 overlay={ 
 \draw[line width=1pt,purple!65!blue]([xshift=-3pt,yshift=.6cm]frame.north 
west)--([xshift=-3pt]frame.south west); 
 \draw[rounded corners=20pt,line width=1pt,purple!65!blue] ([xshift=-
3pt]frame.south west) -- (frame.south east)--(frame.north east); 
 \draw ([yshift=.6cm]frame.south east)--(frame.north east)--
([xshift=10cm]frame.north west); 
 } 
}
\begin{document} 
\begin{myex} 
What is meant by \textbf{electron affinity}. 
\end{myex} 
\end{document}

Vielen Dank im Voraus für Ihre Hilfe

Etwas wie das?

Der Code

\documentclass{article}
\usepackage{lipsum}
\usepackage[many]{tcolorbox} 
\tcbuselibrary{skins}
\xdefinecolor{pBlue}{RGB}{102, 53, 153}
\newtcolorbox[auto counter, number within=section]{myex}[1][]{%

  frame hidden, 
  sharp corners, 
  rounded corners=southeast,
  arc=25pt, 
  fonttitle=\sffamily, % \bfseries,
  title=Ex~\thetcbcounter,
  attach boxed title to top left={xshift=5pt}, %, xshifttext=5pt}, 
  boxed title style={%
