Animation of a diagram with the package Smartdiagram

I use smartdiagram to create a circular diagram with automatic animation. I want to use it for a beamer presentation.
I want to show some introducing words on the top of the slide before starting the animation of the smartdiagram. My problem is that the smartdiagram always starts at the same time with the demonstration of the slide and not after the introduction. Like in my example the animation of the first module of the smartdiagram should start with keyword 1, then module two with keyword 2 and module 3 with keyword 3. I try to handle it with pause but I didn’t manage it. Maybe you can help me.

Many thanks for your efforts!

Example Code:

documentclass{beamer} 
usepackage{smartdiagram}

begin{document}
begin{frame}
 frametitle{frametitle}
  a few introducing remarks ...[0.3cm] 
begin{minipage}{dimexpr.5linewidth-1emrelax}
  begin{enumerate}[<+->]
    setlength{itemsep}{16pt}
    item keyword 1
    item keyword 2
    item keyword 3
  end{enumerate}
end{minipage}
begin{minipage}{dimexpr.5linewidth-1emrelax}
begin{center}
usetikzlibrary{shapes.geometric} % required in the preamble
smartdiagramset{module shape = ellipse,
 arrow style = <-stealth,
font=scriptsize,
module minimum width=0.8cm,
module minimum height=0.6cm,
text width=1.5cm,
circular distance=1.8cm,
}
smartdiagramanimated[circular diagram:clockwise]{one,two,three}
end{center}
end{minipage}
end{frame}
end{document}
