Inclusive \jpsi \triflow at forward rapidity as function of \pt in different centrality intervals (0--10\%, 10--30\%, 30--50\% and 0--50\%) in \pbpb collisions at \fivenn. The results are compared to the \triflow coefficients at midrapidity for charged pions  and prompt ${\rm D}^{0}$ mesons . The statistical and systematic uncertainties are shown as bars and boxes, respectively. The shaded bands represent the systematic uncertainties from the contribution of non-prompt ${\rm D}^{0}$ mesons.
