Initialize option where no direct connection to NotificationHub is required

[dpuckett]

We are following Microsofts recommended path for device Installation using a back end API to do registrations etc. The backend API is responsible for connecting to the hub and the App does not at all.

Is there a way to Initialize the plugin without the connection strings for the hub, so it can receive/handle notifications only?

If not please can this be added, or documentation explaining how to achieve it.
If initialization is not required for receiving/handling notifications using the plugin, please can this be explained as an option in the docs.
