tkz-euclide drawing compass-mark like for Arc construction

i would like the arcs to appeared only on points I and J
(with dash or not like in the manual example) but not as on the first tex-output. the long lines of circles are not needed. i just would like to show how to get I and J points to determine the Cm point on triangle.

here is my code :

   documentclass{standalone}
   usepackage{tkz-euclide}
   begin{document}

   begin{tikzpicture}[scale=2]

    %triangle
    tkzDefPoint(4,2){A}
    tkzDefPoint(8,3){B}
    tkzDefPoint(6,5){C}
    tkzDrawPolygon(A,B,C)
    tkzDrawPoints(A,B,C)

    %point Cm
    %intersect circles
    tkzInterCC(A,B)(B,A) tkzGetPoints{I}{J}
    %median line
    tkzDrawLine[color=green!50!black,dashed, add=.04 and .04](I,J)

    %test arcs (type compass)
    tkzSetUpCompass[color=blue] %blue don't show up :-(
    tkzDrawArc[delta=10](A,B)(I)
    tkzDrawArc[delta=8](B,I)(A)
    tkzDrawArc[delta=10](B,A)(J)
    tkzDrawArc[delta=8](A,J)(B)
    
    %label points
    tkzLabelPoints[below left](A)
    tkzLabelPoints[below right](B) 
    tkzLabelPoints[above right=2mm](C)
    tkzLabelPoint[above left, red](I){$I$}
    tkzLabelPoint[below right, red](J){$J$}
    tkzDrawPoints(I,J)

    %spec signs
    node[magenta] at ($(A)!0.25!(B)$){$/$};
    node[magenta] at ($(A)!0.75!(B)$){$/$};    
    
    %median line C-Cm
    coordinate (Cm) at ($1/2*(A)+1/2*(B)$);
    tkzDrawPoint(Cm)
    tkzDrawLine[dashed, color=red, add=.1 and .15](C,Cm)
    tkzLabelPoints[below right=2mm, magenta](Cm){$C_m$}

    end{tikzpicture}
    end{document}
