Can't open .drawio files

[sidazhou]

This jupyter extension can't open any files (.drawio) created by drawio-desktop.
However if reversed, drawio-desktop is able to open files (.dio) created by this jupyter extension.

Is this a bug or a feature request?

which drawio-desktop:
https://github.com/jgraph/drawio-desktop

[sidazhou]

On closer inspection, .drawio files contain: <mxfile> tags, while .dio uses <mxGraphModel> tags.
Is the conversion straight forward? Any tools available?

We are using an old version of the mxClient library.
