Render Mermaid edited by XML

Is your feature request related to a problem? Please describe.

I use DrawIO-Desktop to edit diagrams. Some of them are generated by external scripts that edit directly the ".drawio" (xml) file.
I also have Mermaid generated graph edited directly in the file.
When I open DrawIO, the mermaid graph location is highlighted with the mermaidData but no SVG/BASE64 render of the graph.

If I click on the empty mermaid graph I have data inserted in the file by script

If I apply the data the graph render appear. So the Mermaid code don't have error.

Describe the solution you'd like
Maybe an option to render Mermaid graph at DrawIO load in a configuration editor. I did many search but no found solution for that kind of feature.

Thanks <3
