Calendar update notification

Hey, I played around a little with the Calendar update notification using tasker. I am trying to make a notification similar to the ones on iOS which states:
Title: Event Updated
Description: "%CALTITLE (added|updated|removed) on %EVENT_START_DATE

How would I go about automating this using Tasker? The "Event Edit" update listener doesnt seem to work for me with the %CALTITLE..

Does anyone have a similar automation which they could share or some guidance on how to automate this? Thanks!
