To view the icon you have used for your PWA Application you are now able view this from a link inside the PWA Creator tool.
When you have the app open in the editor that you want to check the icon for, navigate to the Plugins section on the left menu, and then in the sub menu choose the PWA Creator option.
From here, you can click the View PWA Icon button that you see under the tab Generate & Publish PWA.
Clicking this button will open a new tab in your browser that contains the image that you used when you last generated your PWA application.
