Unable to setup Progressive Web App using AEM SPA editor with Angular

I am trying to setup an SPA in AEM using Angular with PWA features supported.

I have followed the steps mentioned at this link SPA Editor Project | Getting Started with the AEM SPA Editor and Angular | Adobe Experience Manager.

And I was able to setup the SPA using Angular in AEM.

I need to add Progressive Web App features to this setup.

In documentation I found PWA related steps for React but were not able to find anything specific to Angular.

Sample PWA steps for React could be found here Experience League Intelligent Guidance | Adobe (azureedge.net)

Version

AEM - 6.5 AMS

SP - 12

Angular - 15

We are looking for sample implementation so that it could help us setting up our environment.

Thanks,

Juber
