When I try to compile the following
\documentclass{article}
\usepackage{tabularray}
\UseTblrLibrary{functional}
\IgnoreSpacesOn
\prgNewFunction \test {} {
\cellSetText{1}{1}{modfied}
}
\IgnoreSpacesOff
\begin{document}
\begin{tblr}[process=\test]{
width=50mm,
colspec={XX}}
original & original\
original & original\
\end{tblr}
\end{document}
with pdflatex test.tex I get the following:
This is pdfTeX, Version 3.141592653-2.6-1.40.22 (TeX Live 2022/dev/Debian) (preloaded format=latex)
restricted \write18 enabled.

?
It seems that the functional package is not part of my (vanila) TeX live installation. Is this a known issue or is there something wrong with my installation or my code ?
Thank you for your help,
