[Tex/LaTex] Beamer – specify logo position in title page

Question

I placed the logo in my title page but I'm not happy with the positioning, I would like it to be at the bottom right, next to author and date.

\documentclass{beamer}
\usetheme[sectionpage=none, progressbar=frametitle, numbering=fraction]{metropolis}        % Use metropolis theme  
\title{Title}
\date{\today}
\author{Author}
\institute{Title}

% logo of my university
\titlegraphic{\includegraphics[width=2cm]{img/politologo.png}} 

\AtBeginSection[]{
\begin{frame}{Talk Overview}
\tableofcontents[currentsection]
\end{frame}
\frame{\sectionpage}
}

\begin{document}
\maketitle
\end{document}

Answer 1

The position of the title graphics is determined by the theme. In this case it seems to be placed in the top left side of the slide. A quick (and a bit hacky) way to move it is to put it in a picture environment with zero width and height, and then place it where ever you like.

\documentclass{beamer}
\usetheme[sectionpage=none, progressbar=frametitle, numbering=fraction]{metropolis}        % Use metropolis theme  
\title{Title}
\date{\today}
\author{Author}
\institute{Title}

% logo of my university
\titlegraphic{%
  \begin{picture}(0,0)
    \put(305,-120){\makebox(0,0)[rt]{\includegraphics[width=2cm]{example-image}}}
  \end{picture}}
\AtBeginSection[]{
\begin{frame}{Talk Overview}
\tableofcontents[currentsection]
\end{frame}
\frame{\sectionpage}
}

\begin{document}
\maketitle
\end{document}

Play with the argument for \put to get it where you like.
