# How to hyperlink to section title frame

I am using the mtheme for LaTeX Beamer. This theme inserts a title frame with the section title at the beginning of each section.

\AtBeginSection[]
{
\begingroup
\setbeamercolor{background canvas}{parent=palette primary}
\begin{frame}[plain]
\vspace{2em}\usebeamerfont{section title}
\progressbar@sectionprogressbar%
\end{frame}
\endgroup
}


How can I hyperlink to this frame? Labeling the section is obviously not sufficient to be able to link to this frame.

Luckily beamer provides a command for this: \hyperlinksectionstart{text}

\documentclass{beamer}

\AtBeginSection{
\begin{frame}[plain]
\insertsection
\end{frame}
}

\begin{document}

\section{sec1}
