Peace, mercy, and blessings of God be upon you.
I have this piece (plain) that was installed in an Accent 2017, but I replaced it with a button, so I don't need it.
It is shown where it is installed in the last picture (in the red circle) to the left of the steering wheel (next to the traction control button), and I think it fits most other models with the same shape.
Note:
It is shown in the picture (in the blue circle) that the clips that hold it are broken, so it may not be installed as required, and this is to inform you.
