Documentation corrections for Activity Log backend - Creating Custom Events

while following this procedure (https://docs.laravel-enso.com/backend/activity-log.html#creating-custom-events) there were some slight deviation from the documentation - maybe forgotten update.
@reviewer - please check if there is a missing step (maybe on Model - does it have to implement some kind of contract as well? or maybe use some Trait? - because just following these steps the Custom Event is not triggered
