Adding a footnote in a section title slide in beamer

Question

I would like to add an individual footnote in the title pages generated foreach section.

I am sharing a minimal working example below.

\documentclass[hyperref={pdfpagelabels=false}]{beamer} 
\usetheme{CambridgeUS}
\usecolortheme{beaver}
\useoutertheme[footline=authortitle]{miniframes}
\setbeamercolor{footnote}{fg=red}
\setbeamercolor{footnote mark}{fg=red}
\setbeamercolor{section page}{fg=black, bg= darkred!50}
\AtBeginSection[]{
    \begin{frame}
    \vfill
    \centering
    \begin{beamercolorbox}[sep=12pt,center,shadow=true,rounded=true]{section page}
        \usebeamerfont{title}%
        \textit{Section \thesection~}%
                {\color{black} \insertsectionhead}\par%
    \end{beamercolorbox}
    \vfill
    \end{frame}
}
\begin{document}
\section{My section}
\begin{frame}{My slide}
    Some text here. 
\end{frame}
\end{document}

I have tried the following trick, but it did not work.

\section[My section]{My section\raisebox{.3\baselineskip}{\normalsize\footnotemark}}\footnotetext{Here is my note}

Use \protect\footnote{...}

From https://tex.stackexchange.com/a/153340/161015

\footnote is a fragile command and section (or subsection) titles are moving arguments (meaning they get written to an auxiliary file to be used in the table of contents). Fragile commands break in moving arguments and the standard solution is to protect them with \protect

\documentclass[hyperref={pdfpagelabels=false}]{beamer} 
\usetheme{CambridgeUS}
\usecolortheme{beaver}
\useoutertheme[footline=authortitle]{miniframes}
\setbeamercolor{footnote}{fg=red}
\setbeamercolor{footnote mark}{fg=red}
\setbeamercolor{section page}{fg=black, bg= darkred!50}
\AtBeginSection[]{
    \begin{frame}
        \vfill
        \centering
        \begin{beamercolorbox}[sep=12pt,center,shadow=true,rounded=true]{section page}
            \usebeamerfont{title}%
            \textit{Section \thesection~}%
            {\color{black} \insertsectionhead\protect\footnote{bar}}\par% <<<<<<<<<<<<<<<<<
        \end{beamercolorbox}
        \vfill
    \end{frame}
}
\begin{document}
    \section{My section}
    \begin{frame}{My slide}
        Some text here. 
    \end{frame}
\end{document}

Adding \renewcommand\footnoterule{} in the preamble will remove the red separation rule.
