CLI usage instructions unclear

[mattiagiuffrida-st]

I'm trying to use the CLI tool provided with this package, but with no luck.
With the JS API, I can run the following and get the result I want:

const sassGraph = require('sass-graph');
console.log(sassGraph.parseFile(
  'app/packs/entrypoints/publisher-profile.scss',
  {
    loadPaths: ['app/assets/stylesheets'],
  }
));

But I've been unable to replicate this successfully with the CLI tool.
I've tried the following:

• sassgraph descendents app/packs/entrypoints/publisher-profile.scss
  • Error: Missing directory
• sassgraph descendents -I app/assets/stylesheets app/packs/entrypoints/publisher-profile.scss
  • Error: Missing directory
• sassgraph descendents -I app/assets/stylesheets app/assets/stylesheets/ app/packs/entrypoints/publisher-profile.scss
  • Error: Missing directory
• sassgraph descendents app/assets/stylesheets/ app/packs/entrypoints/publisher-profile.scss
  • No output
