Subscribe to message (Form)

'Subscribe to message' is a form service element that can register for certain push messages. The topic (property: Topic) serves as a filter so that only push messages that are really relevant are received.
If a message with the specified subject is received, the 'Receive message' event is triggered. If the element is deactivated, no more events are triggered.

Tip: A push message can be sent on the server side with the action module Push message to registered clients who have subscribed to the topic. The topic is freely selectable.
