      abstract     = {Correlations between mean transverse momentum $[p_{\rm T}]$
                      and anisotropic flow coefficients $v_{\rm 2}$ or $v_{\rm 3}$
                      are measured as a function of centrality in Pb--Pb and
                      Xe--Xe collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV and 5.44
                      TeV, respectively, with ALICE. In addition, the recently
                      proposed higher-order correlation between $[p_{\rm T}]$,
                      $v_{\rm 2}$, and $v_{\rm 3}$ is measured for the first time,
                      which shows an anticorrelation for the presented centrality
                      ranges. These measurements are compared with hydrodynamic
                      calculations using IP-Glasma and $\rm T_{R}ENTo$
                      initial-state shapes, the former based on the Color Glass
                      Condensate effective theory with gluon saturation, and the
                      latter a parameterized model with nucleons as the relevant
                      degrees of freedom. The data are better described by the
                      IP-Glasma rather than the $\rm T_{R}ENTo$ based
                      calculations. In particular, Trajectum and JETSCAPE
                      predictions, both based on the $\rm T_{R}ENTo$ initial state
                      model but with different parameter settings, fail to
                      describe the measurements. As the correlations between
                      $[p_{\rm T}]$ and $v_{\rm n}$ are mainly driven by the
                      correlations of the size and the shape of the system in the
                      initial state, these new studies pave a novel way to
                      characterize the initial state in relativistic heavy-ion
                      collisions.},
