Customize Interview related notifications in Alerts Composer

Summary:

Hi, i am trying to update the interview scheduled alerts composer template that is sent out to interviewers after the schedule is created (code: IRC_Intrv_Scheduled_Interviewer) . It has some groovy expression based on which the location details are sent, but when i use the same groovy expression as available in the seeded version, it does not evaluate it rather prints the expression itself like below:

Has anyone managed to update the custom notification, can they share how they resolved the groovy expression?
