How to use \floatfoot in a xltabular?

Question

I have a long table, and I used the xltabular package. I use \floatfoot{} for writing notes below each table. However, when I use \floatfoot{} in a xltabular environment, the note is simply ignored. What should I do?

Many thanks in advance.

Here is the code example:

\begin{xltabular}{\textwidth}{lXXXXXXXXXXc}


.... some thing ...
\caption{some caption}
\floatfoot{some notes}
\label{tab:chars_colored} 
\end{xltabular}
