Search for lepton-flavor-violating $Z\\to e\\tau$ and $Z\\to\\mu\\tau$ decays with 139 fb$^{-1}$ of Run 2 $pp$ collision data at a center-of-mass energy of 13 TeV recorded by the ATLAS detector at the LHC. This search exploits leptonically-decaying taus in the final state and is combined with a similar ATLAS search in the final state in which the tau-lepton decays hadronically using the same data set as well as Run 1 data.
