Cannot find Service Worker in chrome application tab

Probably this is a dumb question but after quite some searches I cannot find a solution.
In this guide’s ( image it seems you can look and interact with the service worker even in development mode trough the browser application tab.
But when i try to do the same following the steps of the guide nothing is there. Am I missing something obvious here or this is a common issue?
Some additional infos
I run v-s trough docker
