A search for new top quark interactions is performed within the framework ofan effective field theory using the associated production of either one or twotop quarks with a Z boson in multilepton final states. The data samplecorresponds to an integrated luminosity of 138 fb$^{-1}$ of proton-protoncollisions at $\sqrt{s} =$ 13 TeV collected by the CMS experiment at the LHC.Five dimension-six operators modifying the electroweak interactions of the topquark are considered. Novel machine-learning techniques are used to enhance thesensitivity to effects arising from these operators. Distributions used for thesignal extraction are parameterized in terms of Wilson coefficients describingthe interaction strengths of the operators. All five Wilson coefficients aresimultaneously fit to data and 95% confidence level intervals are computed. Allresults are consistent with the SM expectations.
