Invariant mass distribution for $\pt$ 200 MeV/$c$ (left panel) and $\pt$ distribution for $2.92 < m_{\rm ee} < 3.16$ GeV/$c^2$ (right panel) in the centrality class 70-90% for dielectrons with $|y| < 0.9$ in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV. Measured distributions for J/$\psi$ candidates are shown as black markers and the fit components as coloured lines, as explained in the legend.
