Import from Synology Notes?

Is there a current way to import an .nsx file from Synology Notes into Obsidian (namely, convert into .md files and preserve links)? It appears Synology has all but abandoned the app and hasn’t come out with a new version. I found Kevin Durston’s YANOM https://github.com/kevindurston21/YANOM-Note-O-Matic with lots of references to it on the web but it appears to have been removed. Does anyone have an old version of the Github files or is there something else that can do this?
