Weird noise from 2020 Mazda3 AWD while coasting at low speed

Hello, I recently purchased a 2020 Mazda3 AWD. The vehicle has only 250 miles on it, and I started noticing weird noise (almost like hissing or metal abrasion) from the front side of the vehicle while coasting at low speed. The noise is faint, and occurs when the vehicle is coasting at low speed after brief acceleration. You can hear the noise from the video below, starting at around 3 sec. Any idea?

It's under warranty, correct? Have you taken it in to the dealership, yet? I agree that the noise isn't normal.
