Using tabularray by defining "\\" in a different way

Question

I want to use tabularray tables in lyx by redefining tabular environment. For this aim, I need to use \tabularnewline instead of \\ by \providecommand{\tabularnewline}{\\}. But, if I do this, the table is corrupted as in the figure. What is the reason for this, and how to tackle it?

\documentclass{article}
\usepackage{lmodern}
\usepackage{xcolor}
\usepackage{tabularray}
\providecommand{\tabularnewline}{\}
\begin{document}
\Large{WRONG}: 
\begin{tblr}{|c|c|c|}
    \hline
    \SetRow{lime!20} Item 1 & Item 2 & Item 3 \tabularnewline
    \hline
    text & text & text\tabularnewline
    \hline
\end{tblr}
\vspace{1cm}
\Large{RIGHT}: 
\begin{tblr}{|c|c|c|}
    \hline
    \SetRow{lime!20} Item 1 & Item 2 & Item 3 \
    \hline
    text & text & text\
    \hline
\end{tblr}
\end{document}

tabularray must see a real \\ because it uses that to split the array in rows. So you must tell it to expand \tabularnewline first with [expand=\tabularnewline].

\documentclass{article}
\usepackage{lmodern}
\usepackage{xcolor}
\usepackage{tabularray}
\providecommand{\tabularnewline}{\}
\begin{document}
\Large{RIGHT}: 
\begin{tblr}[expand=\tabularnewline]{|c|c|c|}
    \hline
    \SetRow{lime!20} Item 1 & Item 2 & Item 3 \tabularnewline
    \hline
    text & text & text\tabularnewline
    \hline
\end{tblr}
\end{document}
