 Nuclear modification factor of electrons from semileptonic heavy-flavour hadron decays as a function of $\pT$ in Xe--Xe collisions at $\sqrt{s_{\rm NN}}$ = 5.44 TeV for the 0--20\% (left panel) and 20--40\% (right panel) centrality intervals. Statistical uncertainties (vertical bars) and systematic uncertainties (open boxes) are shown. The filled boxes at $\RAA$ = 1 represent the normalisation uncertainty. Comparisons with the PHSD~, MC@sHQ+EPOS2~ and Djordjevic~ models are displayed.
