Would I know if I accidentally put diesel in a Hyundai Azera?

Basically I stop at a gas station and suddenly like 7 dudes are walking around me so I’m panicking just trying to go quick, really needed gas and my dumbass didn’t have time to think about what I was doing. I clicked 87, but had to use the gas pump (was purple?) next to the diesel because the other regular pump was ripped off or something. I tried to look this up and I think it says I’m fine but just gotta make sure because I’m panicking and it’s my bosses car 🤦🏻‍♀️ surely if it had pumped out diesel, the car would already be showing signs of struggle right? And can a diesel pump even fit into a Hyundai azera gas tank?
Thank you
