Amazon Key allows delivery directly into your garage, home, or car to prevent “porch pirates” or weather from affecting your package contents. The Key app allows other apps to link. My garage door app is linked to enable the feature. If you own an amazon cloud cam, it will sync a short video with you delivery person’s access and send it to you. I use a Wyze cam monitoring my garage instead, but lack the ability to link to the Amazon Key app and have it sync a video with my delivery. Since Wyze cams are already enabled for Amazon’s Alexa, it would be great to see this feature investigated also.
as a temporary alternative, you could use the contact sensors on whatever entrance way they would be using so when they open the door it would activate the camera you have in the vicinity.
