Inu Games - Modular Snap System Runtime

The documentation says that:

“Parameters of the plugin can be accessed from Level Editor toolbar “Settings” menu or in “Plugins” section of Project Settings. Parameters are saved in EditorPerProjectUserSettings.ini config file.”

I have the plugin installed, but there is no parameter settings in my project settings/Plugins. MSSR isn’t even listed there. Any thoughts on how to fix that?
