The detector, featuring\n  ultra-thin silicon nitride windows and multiple veto systems,\n  collected approximately 160 hours of solar tracking data between\n  2017-2018. Using machine learning techniques and the veto systems,\n  we achieved a background rate of\n  $1.06\\times 10^{-5}\\,\\text{keV}^{-1}\\text{cm}^{-2}\\text{s}^{-1}$ at a signal efficiency of\n  about $80\\,\\%$ in the $0.2$-$8\\,\\text{keV}$ range.
