Configure motion tracking zone.. D1 max

Trying to configure motion tracking zone. The camera is parking (at rest) at an angle, not facing straight ahead. I read something about customizing motion zones but cannot find it. So basically while I have it pointed towards my front door it rests pointed towards my garage. All I find is a quick start guide, no detailed manual. Thank you.

In the app, choose the settings for that camera then activate the motion detection feature. Tap on ‘detection zone ‘ then the camera view should come up with a shaded area you can drag and customize.
