Splitting longtblr across beamer frames

Question

I've seen nowhere an option to split a longtblr into several beamer frames, does this feature exists ?

If not, is there a mean to perform this ?

Here is a MWE :

\documentclass{beamer}
\usepackage{tabularray}
\UseTblrLibrary{counter} %% added this line
\NewTblrTheme{fancy}{
    \SetTblrStyle{firsthead}{font=\bfseries}
    \SetTblrStyle{firstfoot}{fg=blue2}
    \SetTblrStyle{middlefoot}{\itshape}
    \SetTblrStyle{caption-tag}{red2}
}
\begin{document}
\begin{frame}{Title}

   \begin{longtblr}[
        theme = fancy,
        caption = {A Long Long Long Long Long Long Long Table},
        entry = {Short Caption},
        label = {tblr:test},
        note{a} = {It is the first footnote.},
        note{$\dag$} = {It is the second long long long long long long footnote.},
        remark{Note} = {Some general note. Some general note. Some general note.},
        remark{Source} = {Made up by myself. Made up by myself. Made up by myself.},
        ]{
         colspec = {XXX}, width = 0.85\linewidth,
         rowhead = 2, rowfoot = 1,
         row{odd} = {gray9}, row{even} = {brown9},
         row{1-2} = {purple7}, row{Z} = {blue7},
        }
        \hline
        Head & Head & Head \\
        \hline
        Head & Head & Head \\
        \hline
        Alpha & Beta & Gamma \\
        \hline
        Epsilon & Zeta\TblrNote{a} & Eta \\
        \hline
        Iota & Kappa\TblrNote{$\dag$} & Lambda \\
        \hline
        Nu & Xi & Omicron \\
        \hline
        Rho & Sigma & Tau \\
        \hline
        Phi & Chi & Psi \\
        \hline
        Alpha & Beta & Gamma \\
        \hline
        Epsilon & Zeta & Eta \\
        \hline
        Iota & Kappa & Lambda \\
        \hline
        Nu & Xi & Omicron \\
        \hline
        Rho & Sigma & Tau \\
        \hline
        Phi & Chi & Psi \\
        \hline
        Foot & Foot & Foot \\
        \hline
    \end{longtblr}


    \frametitle{TEST}

\end{frame}

\end{document}

You can manually split the table using \pagebreak:

\documentclass{beamer}
\usepackage{tabularray}
\UseTblrLibrary{counter} %% added this line
\NewTblrTheme{fancy}{
    \SetTblrStyle{firsthead}{font=\bfseries}
    \SetTblrStyle{firstfoot}{fg=blue2}
    \SetTblrStyle{middlefoot}{\itshape}
    \SetTblrStyle{caption-tag}{red2}
}
\begin{document}
\begin{frame}[allowframebreaks]{Title}

   \begin{longtblr}[
        theme = fancy,
        caption = {A Long Long Long Long Long Long Long Table},
        entry = {Short Caption},
        label = {tblr:test},
        note{a} = {It is the first footnote.},
        note{$\dag$} = {It is the second long long long long long long footnote.},
        remark{Note} = {Some general note. Some general note. Some general note.},
        remark{Source} = {Made up by myself. Made up by myself. Made up by myself.},
        ]{
         colspec = {XXX}, width = 0.85\linewidth,
         rowhead = 2, rowfoot = 1,
         row{odd} = {gray9}, row{even} = {brown9},
         row{1-2} = {purple7}, row{Z} = {blue7},
        }
        \hline
        Head & Head & Head \\
        \hline
        Head & Head & Head \\
        \hline
        Alpha & Beta & Gamma\\
        \hline
        Epsilon & Zeta\TblrNote{a} & Eta \\
        \hline
        Iota & Kappa\TblrNote{$\dag$} & Lambda \\
        \hline
        Nu & Xi & Omicron \\
        \hline
        Rho & Sigma & Tau \\
        \hline
        Phi & Chi & Psi \\
        \hline
        Alpha & Beta & Gamma \\\pagebreak

        \hline
    \end{longtblr}
