000002023 520__ $$aThis note presents plots for rediscovery of the $D^{*+}\to D^0\pi^+$, $D^0\to\K^0_S\pi^+\pi^-$ decays, using the data collected by Belle II during 2019, which correspond to 9.6\fb^{-1} of integrated luminosity. The fit to $M(D^0)$ vs $Q$ 2D distribution, fit to $D^0$ decay-time and Dalitz distributions are shown in this note.
