+- https://github.com/eclipse-sirius/sirius-web/issues/2703[#2703] [diagram] Remove the explorer menu used to export diagrams as SVG image.
+This menu was using Sprotty export, which has been replaced by ReactFlow by default (see https://github.com/eclipse-sirius/sirius-web/issues/2671[#2671]).
+The only way to export diagram as SVG image is to use the ReactFlow toolbar located at the top left of each diagram.
