Bibliography not showing in the last slide

Question

I am writing a presentation in Beamer, with the package biblatex. To keep the (few) citations compact in the slides I used \footcite, but at the end of the presentation the usual \bibliographystyle followed by \bibliography does not work. If for example I write:

\begin{frame} 
\bibliographystyle{plain}
\bibliography{bibliography.bib}
\end{frame}

I get the last slide with only "bibliography.bib" written on it. What am I doing wrong?

EDIT: My code is something like this

\usepackage{biblatex}
\begin{document}
\begin{frame}
The article \footcite{Mr. X (2000)} shows that apples are very tasty.
\end{frame}
\begin{frame}
\printbibliography
\end{frame}

Where I have a bibtex file in the same Overleaf project (but printbibliograpghy does not admit arguments(?)) and I call, in the foot note, the articles as abbreviations, not as one would do with \cite{}.
