Referencing to unnumbered sections does not work

Question

I have unnumbered sections in my appendix to which I want to refer to specifically.
As the sections are unnumbered, it always just shows the number of the chapter.

My example code:

\documentclass{scrbook}
\usepackage{xr-hyper} %for cross-referencing between documents
\usepackage[hidelinks]{hyperref} % Hyperlinks
\begin{document}
\chapter{Main Document}
Here I refer to appendix \ref{Appendix_1}, appendix \ref{Appendix_2} and appendix \ref{Appendix_3}.
\chapter{Appendix}
\section*{A.1 Appendix 1}
\label{Appendix_1}
My first Appendix.
\section*{A.2 Appendix 2}
\label{Appendix_2}
My second Appendix.
\section*{A.3 Appendix 3}
\label{Appendix_3}
My third Appendix.
\end{document}

It looks like this:

I already tried https://tex.stackexchange.com/a/48610/234353 but that did not work.

Would appreciate any help!

The \label/\ref always references the last stepped counter. Since starred sections are unnumbered, the \labels all refer to the chapter. Why do you use unnumbered sections if you want to reference them? — campa, Feb 04 '21 at 12:31
Because I don't want the appendix to be numbered in the toc. Is there a way to adjust the counter? — Matthias, Feb 04 '21 at 12:42

A \label always points to the last stepped reference counter, so using unnumbered sections cannot work. If you only have one appendix I would use the following dirty trick

\documentclass[paper=a5,openany]{scrbook}% a5,openany only for smaller snapshot
\usepackage{hyperref}
\begin{document}
\tableofcontents
\chapter{Main Document}
\section{Foo}
Here I refer to appendix \ref{Appendix_1},
appendix \ref{Appendix_2} and appendix \ref{Appendix_3}.
\section{Baz}
\addtocontents{toc}{\setcounter{tocdepth}{0}} % remove sections from ToC
\addchap{Appendix} % unnumbered but printed in ToC
\refstepcounter{chapter} % necessary for working bookmarks
\renewcommand{\thesection}{A.\arabic{section}}
\section{Appendix 1}
\label{Appendix_1}
My first Appendix.
\section{Appendix 2}
\label{Appendix_2}
My second Appendix.
\section{Appendix 3}
\label{Appendix_3}
My third Appendix.
\end{document}

Thank you! I actually found another workaround with hyperlinks — Matthias, Feb 04 '21 at 13:16
