A wealth of data on charmonium production from the major LHC experiments has provided strong evidence for (re-)generation as a dominant production mechanism at low transverse momentum. To make further progress in the understanding of the underlying physics we present an important extension of the statistical hadronisation model to describe J/$\psi$ transverse momentum distributions based on input parameters from hydrodynamical simulations. Comparison to the data allows the testing of the degree of thermalisation of charm quarks in the quark-gluon plasma. To this end we will report analyses of the centrality dependence of J/$\psi$ transverse momentum spectra in Pb-Pb collisions at $\sqrt{s_{NN}} = 2.76$ and $5$ TeV. The studies can be naturally extended to the b-quark sector.
