The inability to locate which websites have a PWA is one of the most frustrating things we have to contend with when trying to find and download apps on Chromebooks. It is possible to hit the button in the address bar, but that is not the most elegant solution. It doesn't help the problem of trying to find other PWAs.
The old "chrome://apps" landing page appears to be getting a new look thanks to Kevin. There's a new "App Home" commit that contains links to documents showing what this new iteration would look like and how it would work.
If you open up the chrome browser on your computer, you'll see a list of any chrome apps that are currently installed. There isn't much else you can do besides remove those apps. With "App Home," you'll be able to view and manage all of your installed Chrome apps, but we could see a future where a variety ofPWAs are listed.
It's about as bare bones as you might think, but you can scroll through a list of available PWAs and install them. Once installed, you will be given a few more options, such as being able to decide if the PWA should open in a new window or at startup.

There is an effort to make your apps even more accessible. The modules show up on the new tab page in chrome The Apps module will allow you to view nine of your installed apps, along with another "Apps" button that will show off any of the otherPWAs that are installed.
It's good to see that the Play Store is getting some changes. Even though the app experience is not great in some cases, the PWA version could save you from some irritations. There isn't a way to tell if the version you installed is the one on the Play Store. The redesign of the landing page could make life simpler.
