What code does chrome android use in small apps?

Question

Android

When an Android site, such as instagram.com, is opened, messages from the bottom are shown to add it to the home screen. After some time, a lightweight Instagram application is installed, it has a package name similar to Android System WebView.
Sorry for this very stupid text. What code would be the closest to that lightweight Instagram app on Chrome?
