Ultra-diffuse galaxies offer a powerful laboratory to probe the nature of dark matter in low-density regimes. In this talk, I present a kinematic analysis of two galaxies from the "Looking into the faintEst WIth MUSE" project. By using integral-field spectroscopy of stellar tracers, we derived two-dimensional velocity fields and modeled these systems as rotating systems embedded in spherical dark matter halo. Our analysis is performed within a Bayesian framework, allowing us to connect the observed stellar kinematics to the underlying mass distribution. We considered the standard cold dark matter paradigm alongside alternative scenarios, including fuzzy, self-interacting, and non-minimally coupled dark matter. Our results demonstrate the power of extremely low-surface brightness galaxies as stringent and independent tests of dark matter physics on galactic scales.
