Delivery Notification - Someone was at front door but it didn't open

#1

I’m hoping someone has done this or can get a slow learner (me) started.
I’d like a notification (bulb on) when a delivery has been dropped on my front porch.
I have a porch motion sensor and a front door contact.
If motion becomes active and the door contact status has not changed 3 minutes prior to or 3 minutes after motion sensed, turn on a bulb. TIA
