Should a project created from the starter be a PWA without any changes?

When creating a project based on https://start.vaadin.com/app
I see that the PWA annotation is there but I cannot find a web app manifest file after a maven build with profile production.

According to the documentation:
https://vaadin.com/docs/latest/configuration/pwa#icons

it should be here:
src/main/webapp/

Do I miss a step?

The manifest.webmanifest will be generated at runtime based on the @PWA configuration
