Groovy script to change status when a User responds to Help Desk Request

We need a groovy script to change the status to 'User Responded' as soon as a user responds to Help desk request.

Client is not satisfied with the one provided by Oracle. Since when a request is created via email, the status comes through as 'User Responded' while it should be 'New' .

Groovy script provided by Oracle

Trigger: Before Insert
if (MessageTypeCd == 'ORA_SVC_CUSTOMER_ENTRY')
{
HRHelpDeskRequest?.StatusCd= 'SND_SVC_HRHD_USER_RESPONDED'
}
