在 foreach tikz 链中寻址节点

Question

将两个节点连接起来很容易。我有一个青色节点与圆形节点 X 连接。

现在我有一个链组成圆形节点，我想将洋红色节点框与链中的圆形 7 连接起来。

有人知道我该如何处理链中的节点吗？

\usetikzlibrary {chains}

\begin{document}
\begin{tikzpicture}[growth dir/.store in=\tikzgrowthdir,
    growth dist/.store in=\tikzgrowthdist,growth dir=-90,growth dist=0.1]
 \begin{scope}[start chain=going {at=(\tikzchainprevious.\tikzgrowthdir),
    shift=(\tikzgrowthdir:\tikzgrowthdist),anchor=180+\tikzgrowthdir},
    nodes={on chain,circle,draw,draw,minimum size=1cm}]
  \foreach \X [count=\Y] in {1,2,3,4,5,6,7,8,9,10,11,12,13,14}

  \ifnum\numexpr\Y>5\relax 
  \tikzset{growth dir=-90}
  \fi
   \ifnum\numexpr\Y>10\relax 
  \tikzset{growth dir=-135}
  \fi
  \node {\X};}
 \end{scope} 

% node connection
\node(A) [draw=cyan!20,fill=cyan!20,text width=3cm, rounded corners] at (-4,0) {Description};
\node(X) [draw,circle] at (-2,-2) {X};
\draw[color=cyan!20, line width=1mm] (A.south) |-  (X.west);

\node(A) [draw=magenta!20,fill=magenta!20,text width=3cm, rounded corners] at (-4,-3) {Description};

\end{tikzpicture}
\end{document}
