  We report the observations of two self-lensing pulses from KIC 12254688 in
Transiting Exoplanet Survey Satellite (TESS) light curves. This system,
containing a F2V star and white-dwarf companion, was amongst the first
self-lensing binary systems discovered by the Kepler Space Telescope over the
past decade. Each observed pulse occurs when the white dwarf transits in front
of its companion star, gravitationally lensing the star's surface, thus making
it appear brighter to a distant observer. These two pulses are the very first
self-lensing events discovered in TESS observations. We describe the methods by
which the data were acquired and detrended, as well as the best-fit binary
parameters deduced from our self-lensing+radial velocity model. We highlight
the difficulties of finding new self-lensing systems with TESS, and we discuss
the types of self-lensing systems that TESS may be more likely to discover in
the future.
