Firstly, a Signal must be created in the system to be able to be used when configuring rules. 

Once present in the system, when configuring a rule, a Signal can be added so that it is sent as part of the respons when the conditions of the rule are met, i.e. when the rule is triggered. 

Signals do not replace the main recommendation (such as "Block", "Review" or "Proceed") but complement it, providing additional guidance.

For example:

• If an entity has been flagged for suspicious activity, a "Trigger_Enhanced_Due_Diligence" signal could be issued.
• If additional KYC information is needed, a "Trigger_Digital_KYC_Form" signal might be generated.
• If electronic identification is required, a "Initiate_Electronic_Identification" signal could be sent.
