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}

    ifxinserttitlegraphic@emptyelseusebeamertemplate*{title graphic}fi

    vfill%

    ifxinserttitle@emptyelseusebeamertemplate*{title}fi

    ifxinsertsubtitle@emptyelseusebeamertemplate*{subtitle}fi

    usebeamertemplate*{title separator}

    begin{minipage}[t]{.5textwidth}

    ifxbeamer@shortauthor@emptyelseusebeamertemplate*{author}fi

    ifxinsertdate@emptyelseusebeamertemplate*{date}fi

    ifxinsertinstitute@emptyelseusebeamertemplate*{institute}fi

    end{minipage}

    begin{minipage}[t]{.5textwidth}

    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}

}



title{Metropolis}

subtitle{A modern beamer theme}

author{Matthias Vogelgesang}

institute{Center for modern beamer themes}

date{}



begin{document}

maketitle

end{document}

If I understand your question correctly, the answer in my comment can help us. Changing includegraphics with minipage environment in that answer, following code is extracted.

documentclass{beamer}



usetheme[numbering=none,block=fill]{metropolis}



%setbeamerfont{frametitle}{size=normalsize,series=normalfontbfseries}

setbeamerfont{frametitle}{size=Huge,series=normalfontbfseries}

setbeamerfont{page number in head/foot}{size=normalsize,series=normalfontbfseries}



setbeamercolor{footline}{fg=black!2, bg=mDarkTeal}

setbeamertemplate{frame footer}{My footline}



makeatletter

setlength{metropolis@frametitle@padding}{0.7ex}% <- default 2.2 ex



setbeamertemplate{footline}{%

    begin{beamercolorbox}[wd=textwidth, sep=0.7ex]{footline}% <- default 3ex

        usebeamerfont{page number in head/foot}%

        usebeamertemplate*{frame footer}

        hfill%

        usebeamertemplate*{frame numbering}

    end{beamercolorbox}%

}



setbeamertemplate{frametitle}{%

  nointerlineskip%

  begin{beamercolorbox}[%
