The dependence of \gc{} on the pseudorapidity difference $|\eta_{\alpha} - \eta_{\beta}|$ (left panel), the transverse momentum difference $|p_{{\rm T}_{\alpha}} - p_{{\rm T}_{\beta}}|$ (middle panel), and the average transverse momentum $(p_{{\rm T}_{\alpha}} + p_{{\rm T}_{\beta}})/2$ (right panel) for pairs of particles with same (closed markers) and opposite (open markers) charges from 20--30\% Xe--Xe collisions at $\sqrt{s_{\rm NN}}=5.44$ TeV (red circles) compared to results from 30--40\% Pb--Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV (black squares) . The Pb--Pb and Xe--Xe same-charge points are slightly shifted along the horizontal axis for better visibility in all panels. Bars (boxes) denote statistical (systematic) uncertainties.
