2018 Mazda CX-5

Took my car to get an oil change and asked them to make sure there was enough air in each tire. After I drove off I noticed the tire pressure light was on. I figured I would drive around and it would eventually turn off. It’s now been a week and the light is still Illuminated. Any idea how I can reset it, or what I should try instead? I can confirm the amount of air in each tire is enough as I double checked with a gauge.
