Command-line arguments
On Linux and Mac, Chrome passes one argument to the native app, which is the origin of the add-on that started it, in the form: chrome-extension://[extensionID]. This enables the app to identify the add-on.
On Windows, Chrome passes two arguments: the first is the origin of the add-on, and the second is a handle to the Chrome native window that started the app.
allowed_extensions
In Chrome, the allowed_extensions key in the app manifest is called allowed_origins instead.
App manifest location
Chrome expects to find the app manifest in a different place. See Native messaging host location in the Chrome docs.
