[Tex/LaTex] Add elements on the title page beamer template

Question

I am using the Metropolis Beamer Template https://it.overleaf.com/latex/templates/metropolis-beamer-theme/qzyvdhrntfmr.

How can I put some other words, like supervisor and co-supervisor, in the right side of the title page?

I tried editing the beamerinnerthememetropolis.sty file, but I am not completely understanding how that code works.

You'll have to adjust vertical space, font size, etc., but you can start from this:

\documentclass{beamer}
\usetheme{metropolis}

\setbeamertemplate{title page}{
  \begin{minipage}[b][\paperheight]{\textwidth}
    \ifx\inserttitlegraphic\@empty\else\usebeamertemplate*{title graphic}\fi
    \vfill%
    \ifx\inserttitle\@empty\else\usebeamertemplate*{title}\fi
    \ifx\insertsubtitle\@empty\else\usebeamertemplate*{subtitle}\fi
    \usebeamertemplate*{title separator}
    \begin{minipage}[t]{.5\textwidth}
    \ifx\beamer@shortauthor\@empty\else\usebeamertemplate*{author}\fi
    \ifx\insertdate\@empty\else\usebeamertemplate*{date}\fi
    \ifx\insertinstitute\@empty\else\usebeamertemplate*{institute}\fi
    \end{minipage}
    \begin{minipage}[t]{.5\textwidth}
    \vspace*{2em}
    {\tiny Super Visor: Super Visor's name%
    \par}
    \vspace*{1em}
    {\tiny Co supervisor: Co supervisor's name%
    \par}
    \end{minipage}
    \vfill
    \vspace*{1mm}
  \end{minipage}
}
