Diagram saving issue
The Jupyter launcher provides a "Diagram" button starting the DrawIO tool, a tool used to draw diagrams.
To save a diagram, it is necessary to use JupyterLab menu with "File" then "Save Diagram" (CTRL+S) or "Save Diagram As..." (CTL+SHIFT+S). Don't use DrawIO interface menu which generates an error. To export the diagram, again use JupyterLab "File" menu then "Export Diagram As SVG" instead of DrawIO "File" menu.
