Rough idle but smooth acceleration and drive. Advice?

I wish I could remember how my car idled when I purchased it but I’m pretty sure it wasn’t this rough. I have a 2015 Elantra Sport and at idle there’s a distinct vibration that’s hurting me. I had the spark plugs changed, and it helped the drive but the idle is still unsteady. Can anyone help?

If the idle speed is correct, clean the throttle body or check to see if it is clogged with deposits.
