Groovy and Notification Examples

Summary:

Can anyone share their trigger and groovy script for common notifications for HR Help Desk?

I have been able to create a few around changed attributes, like when a queue is changed, or when an SR gets assigned or reassigned, but I am looking for triggers around messages, and to the team of a queue when an SR is created but has not been assigned. I did you the examples from Oracle, but expanded on the messages

SR Assigned

Trigger : Before Update

 if (isAttributeChanged('AssigneeResourceId')) {

   try {

       def recipientPartyId = AssigneeResourceId

       def messageText = '"SR' + SrNumber + ' - ' + Title+'" has been assigned to you in queue "' + SvcQueue?.QueueName+'"'
