I have some unbreakable variable height sidebyside tcolorboxes.
At the bottom of those boxes I want to have on the left side a line, and on the right side a "please seperate here" text on the same level as the line.
I have no fixed height, so I cannot set this attribute (?).

\usepackage[many]{tcolorbox}

\begin{document}
\begin{tcolorbox}[sidebyside,sidebyside align=top]
on left: \lipsum[1]
\vfill
\mbox{}{ \hrule}
\tcblower
text
\vfill
please separate here
\end{tcolorbox}
\begin{tcolorbox}[sidebyside,sidebyside align=top]
text
\vfill
\mbox{}{ \hrule}
\tcblower
on right:\lipsum[2]
\vfill
please separate here
\end{tcolorbox}
