Broken part front bumper

Hi guys new to this site. I recently noticed my car is missing a small square-type piece from the front bumper on the drivers side. It's unknown if it broke off or some sick individual stole it for whatever reason. Anyways, what part would I look for in order to replace it and do you think it would be covered under the standard manufacturers warranty since I just got this car in August of 2019.

Make/Model is 2020 Toyota Corolla LE
