Issue Description:

I'm using next-pwa for my Next.js project, and I have successfully converted my application into a Progressive Web App (PWA). However, I'm facing a challenge in identifying whether the PWA is installed or not on both iOS and Android devices to improve the user experience.

Steps to Reproduce:

Implement next-pwa in a Next.js project.
Convert the application to a PWA using the next-pwa plugin.
Attempt to identify the application installation status on both iOS and Android.
Expected Behavior:

I expect to find a way to determine whether the PWA is installed on the user's device, so I can provide an enhanced user experience, such as displaying a custom install banner or enabling additional features for installed users.

Current Behavior:

As of now, I have not found a suitable method or library within the next-pwa documentation or examples to identify the application installation status in both iOS and Android devices.

Any guidance or pointers on how to identify the installation status of a PWA in both iOS and Android using next-pwa would be greatly appreciated.
