This trigger will fire on this device when the specified web URL is called from anywhere.
Note
that the URL is unique to this device and the URL will change if the application is reinstalled (or all application data is deleted).
This feature uses Firebase Cloud Messaging to notify the device via the backend server, therefore it is not functional on devices that lack Google services (such as Alexa tablets etc.)
