TL;DR: Search for the lepton-flavor violating decay of the Higgs boson and additional Higgs bosons in the eμ final state in proton-proton collisions at 13 TeV finds no evidence for such decays. The observed upper limit on the eμ branching fraction for the Higgs boson is 4.4 (4.7) $\times$ 10$^{-5}$ at 95% confidence level.
