Notification/Event at the end of a delay period

Hello Community; Is there a way of triggering a Notification/Event at the end of a delay period ? cheers; Piotr

you want the trigger to happen from inside the app?
(which means that are you sure that the app will still be open after that time in order for the trigger to work?)

Thanks; This is related to the other question of mine: Is there a way to cancel a running delay function when switching the context?
