Charge-dependent two- and three-particle correlations measured in Xe-Xecollisions at $\sqrt{s_{\mathrm{NN}}} = 5.44$ TeV are presented. Results areobtained for charged particles in the pseudorapidity range $|\eta|<0.8$ andtransverse momentum interval $0.2 \le p_{\rm T}<5.0$ GeV/$c$ for differentcollision centralities. The three-particle correlator ${\gamma_{\alpha\beta}}\equiv {\langle \cos(\varphi_\alpha + \varphi_\beta - 2{\Psi_{\rm 2}})\rangle}$, calculated for different combinations of charge sign $\alpha$ and$\beta$, is expected to be sensitive to the presence of the Chiral MagneticEffect (CME). Its magnitude is similar to the one observed in Pb-Pb collisionsin contrast to a smaller CME signal in Xe-Xe collisions than in Pb-Pbcollisions predicted by Monte Carlo (MC) calculations including a magneticfield induced by the spectator protons. These observations point to a largenon-CME contribution to the correlator. Furthermore, the charge dependence of${\gamma_{\alpha\beta}}$ can be described by a blast wave model calculationthat incorporates background effects and by the Anomalous Viscous FluidDynamics model with values of the CME signal consistent with zero. The Xe-Xeand Pb-Pb results are combined with the expected CME signal dependence on thesystem size from the MC calculations including a magnetic field to obtain thefraction of CME contribution in ${\gamma_{\alpha\beta}}$, $f_{\rm CME}$. TheCME fraction is compatible with zero for the 30% most central events in bothsystems and then becomes positive; averaging over the 0-70% centrality intervalyields an upper limit of 2% (3%) and 25% (32%) at 95% (99.7%) confidence levelfor the CME signal contribution to ${\gamma_{\alpha\beta}}$ in Xe-Xe and Pb-Pbcollisions, respectively.
