Insert letter before citation with biblatex/biber only in one `refsection`

Question

I want to insert a letter (eg. "S") before citations both in text and in the bibliography. I've found a similar question here:

How to add a letter before the number of citation in the text?

However:

I want to do it for only a refsection,
with the using of biblatex/biber.

But I have no idea how. My MWE:

\documentclass{article}
\usepackage[sorting=none,backref=false]{biblatex}
\bibliography{\jobname.bib}
\begin{document}
\section{Considered as refsection 0}
This is a normal citation: \cite{NiInt_3}.
\section{Refsection1}
\begin{refsection}
I want to cite this \cite{NiInt_1} as [S1] here and in the bibliography.
\printbibliography[keyword=withletter, title={With letter}]
\end{refsection}
\printbibliography[title={Without letter}]
\end{document}

You can use \newrefcontext[labelprefix=S] in a refcontext:

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
  @book{lamport1994latex,
    title={LATEX: a document preparation system: user's guide and reference manual},
    author={Lamport, Leslie},
    year={1994},
    publisher={Addison-wesley}
  }
  @book{mittelbach2004latex,
    title={The LATEX companion},
    author={Mittelbach, Frank and Goossens, Michel and Braams, Johannes and Carlisle, David and Rowley, Chris},
    year={2004},
    publisher={Addison-Wesley Professional}
  }
\end{filecontents}
\usepackage[sorting=none,backref=false]{biblatex}
\bibliography{\jobname.bib}
\begin{document}
\section{Considered as refsection 0}
This is a normal citation: \cite{mittelbach2004latex}.
\section{Refsection1}
\begin{refsection}
\newrefcontext[labelprefix=S]
I want to cite this \cite{lamport1994latex} as [S1] here and in the bibliography.
\printbibliography[title={With letter}]
\end{refsection}
\printbibliography[title={Without letter}]
\end{document}

I've just copy-pasted your answer, but does not work: every citation is preceded by "S". Do you have any idea, what could be wrong? – Tom Solid Oct 23 '20 at 12:52
Did you run the MWE unchanged? – DG' Oct 23 '20 at 13:46
Yes. Just copy-paste, pdflatex, biber, pdflatex, pdflatex. – Tom Solid Oct 23 '20 at 16:23
Curious. Are you running an up to date system? – DG' Oct 23 '20 at 16:27
I think so. I have installed texlive packages about 2 years ago together with the OS (Opensuse 15.1). – Tom Solid Oct 23 '20 at 16:32

Try installing a more recent version of TeX Live (you might also be interested in this answer: https://tex.stackexchange.com/a/187379/29873) – DG' Oct 23 '20 at 19:02
I have updated Texlive and now it works. Thank you for your kind help! – Tom Solid Oct 26 '20 at 14:29
