Change the label display value

Question

I have a custom command to display pseudocodes using tcolorbox. The \newtcblisting command creates a custom counter to display the boxes. I'm trying to reference the pseudocodes somewhere in the document showing this custom counter but I only managed to show the chapter counter using \ref.

Here's a sample code:

\documentclass{article}
\usepackage{graphicx} % Required for inserting images
\usepackage[most]{tcolorbox}
\usepackage{minted}
\usepackage[
      colorlinks=true,
]{hyperref} 
\usepackage{etoolbox}
\begin{document}
\newtcblisting[auto counter,list inside=mypseudocodes]{pseudocodeV1}[3][]{%
  list entry={\thesection.\protect\numberline{\thetcbcounter}#2},
  title={Pseudocode \thesection.\thetcbcounter\label{pseudocode:#3}: #2},
  listing options={tabsize=2,escapeinside=||,mathescape=true},
  listing only,
  enhanced,
  #1
}
\newtcblisting[auto counter,list inside=mypseudocodes]{pseudocodeV2}[3][]{%
  list entry={\thesection.\protect\numberline{\thetcbcounter}#2},
  title={Pseudocode \thesection.\thetcbcounter\def@currentlabel{Custom ref Text}{\label{pseudocode:#3}}: #2},
  listing options={tabsize=2,escapeinside=||,mathescape=true},
  listing only,
  enhanced,
  #1
}
\tcblistof[\section*]{mypseudocodes}{List of Pseudocodes}
\addcontentsline{toc}{chapter}{List of Pseudocodes}
\section{Test1}
PseudocodeV1: \ref{pseudocode:code} \
\noindent
PseudocodeV2: \ref{pseudocode:code2} \
\section{Test2}
\begin{pseudocodeV1}{
   My Title
}{code}
a = 1;
a = 2;
\end{pseudocodeV1}
\section{T1}
\begin{pseudocodeV2}{
   My Title
}{code2}
a = 1;
a = 2;
\end{pseudocodeV2}
\end{document}

Anyone knows why the command \def\@currentlabel{}{} isnt working or can suggest any workarround?

I've got the \def\@currentlabel{}{} suggestion from: Labeling a text and referencing it later

The problem was fixed by adding \makeatletter before \newtcblisting! Credit to Ulrike Fischer for the solution in the comments.

The code below illustrates the solution:

\documentclass{article}
\usepackage{graphicx} % Required for inserting images
\usepackage[most]{tcolorbox}
\usepackage{minted}
\usepackage[
      colorlinks=true,
]{hyperref} 
\usepackage{etoolbox}
\begin{document}
\makeatletter
\newtcblisting[auto counter,list inside=mypseudocodes]{pseudocode}[3][]{%
  list entry={\thesection.\protect\numberline{\thetcbcounter}#2},
  title={Pseudocode \thesection.\thetcbcounter\def@currentlabel{\thesection.\thetcbcounter}{\label{pseudocode:#3}}: #2},
  listing options={tabsize=2,escapeinside=||,mathescape=true},
  listing only,
  enhanced,
  #1
}
\newtcblisting[auto counter,list inside=mypseudocodes]{pseudocodeWText}[4][]{%
  list entry={\thesection.\protect\numberline{\thetcbcounter}#2},
  title={Pseudocode \thesection.\thetcbcounter\def@currentlabel{Some Custom Text: #4}{\label{pseudocode:#3}}: #2},
  listing options={tabsize=2,escapeinside=||,mathescape=true},
  listing only,
  enhanced,
  #1
}
\makeatother
\tcblistof[\section*]{mypseudocodes}{List of Pseudocodes}
\addcontentsline{toc}{chapter}{List of Pseudocodes}
\section{Test1}
Pseudocode: \ref{pseudocode:code1} \
Pseudocode: \ref{pseudocode:code2} \
\section{Test2}
\section{T1}
\begin{pseudocode}{
   My Title
}{code1}
a = 1;
a = 2;
\end{pseudocode}
\begin{pseudocodeWText}{
   My Title
}{code2}{Display Text}
a = 1;
a = 2;
\end{pseudocodeWText}
\end{document}
