I'd like to install this plugin

However, adding the following options to redactor.yaml file doesn't seem to work:

definedLinks: '/_app/core/bundles/redactor/redactor/defined-links.json'
plugins: ['definedlinks']

Has anyone added this plugin? Does anyone have any bright ideas for how this defined list might be dynamically populated with page content? If that were possible, users wouldn't have to think about page urls. Ideally, the plugin would have a predictive search field for sites with tons of articles but I'm not savvy enough to write something like that, so I'll just keep crossing my fingers.
