                      $D_s^+$ mesons were measured as a function of transverse
                      momentum (p$_T$) in Pb–Pb collisions at a centre-of-mass
                      energy per nucleon pair $\sqrt {s_{NN}}$ = 5.02TeV collected
                      with the ALICE detector at the LHC. $D_s^+$ mesons and their
                      charge conjugates were reconstructed at midrapidity
                      (|y|<0.5) from their hadronic decay channel $D_s^+$ →
                      ϕπ$^+$, with ϕ→K$^−$K$^+$, in the p$_T$ intervals 2 <
                      p$_T$ < 50GeV/c and 2 < p$_T$ < 36GeV/c for the 0–10\% and
                      30–50\% centrality intervals. For p$_T$ > 10GeV/c, the
                      measured $D_s^+$-meson nuclear modification factor R$_{\rm
                      AA}$ is consistent with the one of non-strange D mesons
                      within uncertainties, while at lower p$_T$ a hint for a
                      $D_s^+$-meson R$_{\rm AA}$ larger than that of non-strange D
                      mesons is seen. The enhanced production of $D_s^+$ relative
                      to non-strange D mesons is also studied by comparing the
                      p$_T$-dependent $D_s^+$/$D^0$ production yield ratios in
                      Pb–Pb and in pp collisions. The ratio measured in Pb–Pb
                      collisions is found to be on average higher than that in pp
                      collisions in the interval 2 < p$_T$ < 8 GeV/c with a
                      significance of 2.3σ and 2.4σ for the 0–10\% and
                      30–50\% centrality intervals. The azimuthal anisotropy
                      coefficient v$_2$ of prompt $D_s^+$ mesons was measured in
                      Pb–Pb collisions in the 30–50\% centrality interval and
                      is found to be compatible with that of non-strange D mesons.
                      The main features of the measured R$_{\rm AA}$,
                      $D_s^+$/$D^0$ ratio, and v$_2$ as a function of p$_T$ are
                      described by theoretical calculations of charm-quark
                      transport in a hydrodynamically expanding quark–gluon
                      plasma including hadronisation via charm-quark recombination
                      with light quarks from the medium. The p$_T$-integrated
                      production yield of $D_s^+$ mesons is compatible with the
                      prediction of the statistical hadronisation model.},
