Strange white moving object South Chicago Suburbs around Halloween 2020

I was driving in a car with another passenger, around noon on the approximate date of October 29th/30th of 2020. We were at Sauk Trail and Western Avenue where I noticed a white oval/rectangle shape moving in the sky west to east. It had no other color to it. The closest object I can think of that it looked like was a helicopter but it was all white which most helicopters are not. It then moved along going lower to where it disappeared behind trees and was no longer visible. It did not move any faster than a usual object in the sky such as a helicopter or plane but it was very unusual and of a single white color. It was absolutely not a cloud. It made no audible noise, no lights of any kind, no unusual speed, in fact the thing most strange about it was just that, that it was of such uniform color white/off white. The shape was also strange as it appeared generally close but looked like a roundish oval blob. We both saw the object and are very perple! xed by it.
