This plugin handles the general bureaucratic management for Nginx configurations around changes to an app, like its renaming or deletion.
This plugin does not handle any actual creation of Nginx configurations for apps. Configurations for apps are created and updated in plugins like plushu/plushu-app-nginx-servers (writing Nginx server definitions for an app's defined domains) or plushu/plushu-app-nginx-upstream-docker (linking an app's defined Nginx servers to the local Docker container for that app).
