# Latex Beamer - Vertically center aligned text to the left of tcolorbox

I want to place three tcolorboxes among themselves with arrows between them. To the left of each colorbox is a text that should be center aligned with respect to the box.

The following code produces the boxes, arrows and texts, but I miss the vertical center alignment.

\begin{tabularx}{0.5\textwidth}{p{0.6cm}c}
1979 &
\begin{tcolorbox}[colframe=tubsred,colback=white,arc=4pt,
left=6pt,right=6pt,top=6pt,bottom=6pt,boxsep=0pt,width=0.7\textwidth, halign = center]
Text A
\end{tcolorbox} \\
%
& \begin{tikzpicture}[line cap = round]
\draw[tubsred, line width = 3pt, ->] (0,0) -- (0,-0.5);
\end{tikzpicture} \\
%
1992 &
\begin{tcolorbox}[colframe=tubsred,colback=white,arc=4pt,
left=6pt,right=6pt,top=6pt,bottom=6pt,boxsep=0pt,width=0.7\textwidth, halign = center]
Text B
\end{tcolorbox} \\
%
& \begin{tikzpicture}[line cap = round]
\draw[tubsred, line width = 3pt, ->] (0,0) -- (0,-0.5);
\end{tikzpicture} \\
%
This \newline Work &
\begin{tcolorbox}[colframe=tubsred,colback=white,arc=4pt,
left=6pt,right=6pt,top=6pt,bottom=6pt,boxsep=0pt,width=0.7\textwidth, halign = center]
Text C
\end{tcolorbox} \\
%
\end{tabularx}

What's the best way to achieve this behavior?

Here I use the baseline= key to tcolorbox. For the single line entries, its value should be that of bottom plus the line thickness, estimated here as 7.5pt. For the 2-line entry, I had to add 1/2 of a \normalbaselineskip.
