I am using the latest fontawesome package for latex version 5.9.0 and it seems that not all icons are usable. In thw following MWE \faIcon{phone-alt} says it is not found.
\documentclass{article}
\usepackage{fontawesome5}
\begin{document}
\faIcon{phone}
\faIcon{phone-alt}
\end{document}
I am getting the following error
fontawesome5 error: "icon-not-found" The requested icon phone-alt was not found. For immediate help type H <return>.
EDIT This is the last part of my log file.

Indeed I was not using version 5.9.0 as I thought but 5.8.0. I updated the package and everything works.
