Notify Users About Supply Disruptions feature setup

We are trying to utilize the 25C feature "Notify Users About Supply Disruptions" by defining the appropriate rules however the documentation is not clear enough to complete the setup.

1. Does this feature allow the submitter of the supply line to receive the notification when it fails.
2. If so, how to define the rule under the SupplyExceptionNotify task in the BPM Worklist.

The expectation is to have the alert sent to the user whoever submitted that particular line which has failed and resides at Supply orchestration. We were able to navigate till the Assignees under the BPM Worklist Task configuration, but couldn't understand how to define the attributes to enable the notifications for the submitter. Please elaborate on how the Supplynotificationrule should be defined to achieve the mentioned ask.
