The young M-star TWA 7 hosts a bright and near face-on debris disk, imaged over several decades. The disk displays multiple complex substructures such as three disk components and spiral arms, suggesting the presence of planets to actively sculpt these features. The evidence for planets in this disk was further strengthened with the recent detection of a point-source compatible with a Saturn-mass planet companion using JWST/MIRI. This detection is significant, as the candidate would be the smallest planet ever to be directly-imaged and is also at the same location a planet was predicted to reside based on the disk morphology. Here, we present new observations of the TWA 7 system with JWST/NIRCam in the F200W and F444W filters. In the F444W, we are able to detect faint emission coinciding with the location of the planet candidate imaged with MIRI. Measurements of the candidate's flux with NIRCam further support the candidate as a sub-Jupiter mass planet companion, rather than a background galaxy or brown dwarf. Therefore, TWA 7 provides a rare opportunity to directly study planet-disk interactions and the imprints that planets leave on their debris disks.
