Draw arrow between Venn diagrams

Question

Below is the code:

\documentclass[svgnames,border=5mm]{beamer}

\hypersetup{colorlinks}
\definecolor{bleudefrance}{rgb}{0.19, 0.55, 0.91}
\definecolor{aquamarine}{rgb}{0.5, 1.0, 0.83}
\definecolor{electricyellow}{rgb}{1.0, 1.0, 0.0}
\definecolor{robineggblue}{rgb}{0.0, 0.8, 0.8}
\definecolor{ballblue}{rgb}{0.13, 0.67, 0.8}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[french]{babel}
\usepackage[absolute,overlay]{textpos}
\usepackage{tikz}

\begin{document}

\begin{frame}{Vers une modélisation du milieu complexe}
\begin{columns}
\begin{column}{12cm}
\begin{tikzpicture}[scale=0.9]
\uncover<1->{
  \begin{scope}[blend group = soft light]
  \fill[gray!20!white]   (2.5,3) circle (30pt and 15pt);
    \fill[red!30!white]   ( 90:1.2) circle (2);
    \fill[green!30!white] (210:1.2) circle (2);
    \fill[cyan!30!white]  (330:1.2) circle (2);
    \fill[pink!30!white]   (90:-3.2) circle (2);
  \end{scope}
  \node at (2.5,3)    {Contexte};
  \node at ( 90:2)    {Pluridisciplinarité};
  \node at (-1.5,-0.97)   {Climat};
  \node at ( 330:2)   {\bfseries{\underline{Sol}}};
  \node at ( 90:-3.2)  { \Large Blablabla};
  \node [font=\Large] {Vous};
}
\uncover<2->{
\begin{scope}[xshift=7cm]
  \begin{scope}[blend group = soft light]
  \fill[gray!30!white]   (2.5,3) circle (30pt and 15pt);
    \fill[robineggblue!40!white]   ( 90:1.2) circle (2);
    \fill[bleudefrance!40!white] (210:1.2) circle (2);
    \fill[aquamarine!40!white]  (330:1.2) circle (2);
    \fill[ballblue!40!white]  (90:-3.2) circle (2);
  \end{scope}
  \node at (2.5,3)    {Objectif};
  \node at ( 90:2)    {Caractérisation};
  \node at (-2,-0.98)   {Imagerie};
  \node at (1.5,-0.98)   {Micromécanique};
  \node at ( 90:-3.2)  {Modélisation};
  \node at ( 0,-3.6)  {numérique};
  \node at (0,0) [font=\huge,
      color = black,
      align = center
   ]{
      \bfseries{Sol}
   };
\end{scope}
}

\end{tikzpicture}
\end{column}
\end{columns}
\hspace{1cm}
\end{frame}

\end{document}

which produces two slides

I want to draw an arrow from the nod of the "Sol" in the left Venn diagram pointing towards the word "Sol" to the right one.

The arrows should be as the arrows of this thread

tiki fancy arrow in tikz environment

Thanks in advance.

Just give the nodes some names, and draw an arrow between them.
