  In a cold and stable space environment, the James Webb Space Telescope (JWST
or "Webb") reaches unprecedented sensitivities at wavelengths beyond 2 microns,
serving most fields of astrophysics. It also extends the parameter space of
high-contrast imaging in the near and mid-infrared. Launched in late 2021, JWST
underwent a six month commissioning period. In this contribution we focus on
the NIRCam Coronagraphy mode which was declared "science ready" on July 10
2022, the last of the 17 JWST observing modes. Essentially, this mode will
allow to detect fainter/redder/colder (less massive for a given age)
self-luminous exoplanets as well as other faint astrophysical signal in the
vicinity of any bright object (stars or galaxies). Here we describe some of the
steps and hurdles the commissioning team went through to achieve excellent
performances. Specifically, we focus on the Coronagraphic Suppression
Verification activity. We were able to produce firm detections at 3.35$\mu$m of
the white dwarf companion HD 114174 B which is at a separation of $\simeq$ 0.5"
and a contrast of $\simeq$ 10 magnitudes ($10^{4}$ fainter than the K$\sim$5.3
mag host star). We compare these first on-sky images with our latest, most
informed and realistic end-to-end simulations through the same pipeline.
Additionally we provide information on how we succeeded with the target
acquisition with all five NIRCam focal plane masks and their four corresponding
wedged Lyot stops.
