When is the second part of the tutorial will be working? The PWA react tutorial link to git hub is still giving an error so it´s impossible to download the starting files..and I can´t get the serviceWorker to work :( I have my serviceWorker.js file and import it in my index.js: import register from './serviceWorker'; Then in my index.js I call the function imported: register(); When I update the Firebase hosted app with npm run deploy it compiles correctly and don´t seem to have any errors. However when I go to the hosting (in my case https://agenda-12fff.web.app/) it doesn´t ask me if I want´to install the app or not..I understand there should be a pop up appearing so that I could add the app..but there is no pop up to install it..how can I resolve that??
