It was recently proposed that such a light gauge boson can be detected during the Belle II experiment with a luminosity of 50 ab$^{-1}$ by the $e^+ e^- \\to \\gamma +\\slashed{E}$ process through the kinetic mixing with the photon, where the missing energy $\\slashed{E}$ is from the $Z' \\to \\bar\\nu \\nu$ decays.
