I researched this code logic and found that this repo is only for viewer clients. The logic for handing the open-file ready is in the share-embed script.
Finally, the iframe contains an SVG to display the .xmind file, but we don't know how the xmind file is converted to SVG.
Additionally, I found this archived repo xmind-viewer, it is a lightweight library to parse a .xmind file and render it in SVG.
