Shift curly braces

Question

I want to shift the curly brace of this tikz to the right, but it doesnt seem to work with xshift. How can I achieve this ? This is my code and at the bottom I added a picture of the tikz with the result I am trying to achieve.

\documentclass{article}

\usepackage{graphicx,color}
\usepackage{tikz}
\usetikzlibrary{decorations.pathreplacing,calligraphy}
\usetikzlibrary{arrows}

\begin{document}


\begin{figure}[h!]
    \centering
    \xdefinecolor{darkgreen}{RGB}{76, 153, 0}
    \xdefinecolor{darkblue}{RGB}{0, 102, 204}
    \tikzstyle{block_blue} = [rectangle,fill=darkblue!20, draw=black, thick, align=center,minimum height=4ex, minimum width = 8.5em,rounded corners]
    \tikzstyle{block_green} = [rectangle,fill=darkgreen!30, draw=black, thick, align=center ,minimum height=4ex, minimum width = 8.5em,rounded corners]
    \tikzstyle{block_orange} = [rectangle,fill=orange!20, draw=black, thick, align=center ,minimum height=4ex, minimum width = 8.5em,rounded corners]
    \tikzstyle{line} = [draw, thick, -latex', shorten >=0pt]

    \begin{tikzpicture}[node distance=3.5em]
        \node[block_green](1) {Modell erstellen}; 
        \node[block_orange,right of=1,xshift=3.5cm](2) {TensorFlow,\\PyTorch,\\Caffe};
        \node[block_green,below of=1] (3){AI Optimierer};
        \node[block_green,below of=3] (4){AI Quantisierer};
        \node[block_green,below of=4] (5){AI Kompilierer};
        \node[block_blue,below of=5] (6){Kompiliertes Modell};
        
        \draw (1) [line]-- (3);
        \draw (3) [line]-- (4);
        \draw (4) [line]-- (5);
        \draw (5) [line]-- (6);
        \draw (2) [line]-- (1);

        \draw [decorate,decoration={brace,amplitude=5pt,raise=2ex},xshift=3cm](3.north)--node[block_orange, xshift=2.5cm]{Vitis AI}(5.south);

    \end{tikzpicture}

That is what raise is for.
