Left: example of $\mathrm{D}^{*+}$ raw yield distribution as a function of the selection applied on the BDT output score related to the probability to be non-prompt $\mathrm{D}^{*+}$ mesons in the 30-50% Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV. Right: raw fraction of non-prompt $\mathrm{D}^{*+}$ mesons as a function of $p_\mathrm{T}$ in central (0-10%) and midcentral (30-50%) Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV.
