Nuclear modification factor of electrons from beauty-hadron decays in the $10\%$ most central Pb--Pb collisions at $\sqrt{s_{\rm{NN}}} = 5.02 {\rm TeV}$ compared with predictions from several theoretical calculations. Left: Comparison with predictions from DREENA-B  and DAB-MOD M\&T  models for electrons from beauty and charm decays. Right: Comparison with predictions from MC@sHQ , PHSD , and LIDO  calculations for electrons from beauty decays.
