Mindmap with markmap.js

I put the following in CONFIG (space-lua). Is this correct?

config.set("markmap.source","Library/Malys/MarkmapMindmap")

SilverBullet v2.3.0.

As I recollect, setting this up was relatively painless except for the text in darkmode which you fixed at my request. Feel like I am missing the obvious. It is not working as expected. :expressionless:
