// app shim associated with an (installed) PWA. If showing the OS-native prompt
// in the app shim fails, this will call RecreateView() to fall back to a
// regular chrome permission prompt. Additionally, if the app shim had
// previously been granted OS-level notifications permission, we'll also fall
// back to a regular chrome prompt, rather than automatically granting
// notification permission without showing any prompt.
