Re-Calibrate Android Compass

I have a Nexus 5X and was in a bit of a hurry when I followed the setup steps. There was a calibrate compass wizard, which I skipped because I wanted to do this later. However, I've not figured out yet how to launch the compass calibration wizard again. I found this question on Android.SE telling about the general process, as well as this Google support article , but I couldn't figure out how to launch that wizard again. Any ideas?
