Create a Notification on my Custom Business Object, How to Define Recipients?

Hi experts,

I create a Business Object have a element field Createby, datatype is EmployeeID.

When I create Notification I can choose the field

and set Workflow rules Recipient Determination, I can select the CreatedBy

But I hope the Recipient is sent to My manager or My team on Create the new record.

So I define

[Label("Manager")] [Tooltip("Manager")] element ManagerUUID:UUID;

write Code on Event-AfterModify.absl:

if (employee.IsSet()){

  this.ToEmployee = employee.ToRoot;

  this.ManagerUUID = this.ToEmployee.CurrentOrganisationalUnitAssignment.ToParent.CurrentFunctionalManager.GetFirst().EmployeeUUID;

}

Because I don't how to transfer UUID to ID, So I try to use the UUID Field

Surprisingly, even satisfy my requirement.
when I create a new record Notification to my manager.

Currently, I don't know how to reach another requirement - Sent Notification To My team

Can you give me any idea.

Best regards

Daniel
