Notify User (Service caller)

This component calls Notify User (Service) deployment and sends a custom email message to one or more recipients.

The recipient can be specified either as a Hub user ID or as a plain email address. If a user ID is provided, the component uses the connected credentials to resolve it via a Hub API call.

Component settings can be set manually or via flow variables.
