Addendum: Dielectron production in proton-proton and proton-lead collisions at $\sqrt{s_{\mathrm{N}\mathrm{N}}}$ = 5.02 TeV

This is an addendum to the article [arXiv:2005.11995] “Dielectron production in proton-proton and proton-lead collisions at $\sqrt{s_{\mathrm{N}\mathrm{N}}}$ = 5.02 TeV” published in Phys. Rev. C 102 no. 5, (2020) 055204. We update the extracted charm cross section at midrapidity given in Table 3 and Figure 4 (left) of the original publication with the fragmentation fractions of charm quarks in pp collisions published in Phys. Rev. D 105 (2022) L011103.
