Quarkonia collectivity in large collision systems with ALICE

Quarkonium production is one of the golden probes to study the quark–gluon plasma (QGP). Among many observables, the measurement of azimuthal anisotropies in quarkonium production sheds light on the collective behavior of heavy-flavor particles in a strongly interacting medium. In particular, the measurements of the elliptic flow ($v_2$) of quarkonia in Pb–Pb collisions at the LHC provide us direct evidence of heavy quark thermalization in the QGP. In these proceedings, new results of inclusive $\mathrm{J}\mathrm{/}\psi$ elliptic flow measurement in Pb–Pb collisions carried out by the ALICE collaboration in Run 3 using three methods including event-plane, scalar-product and multi-particle correlation (cumulant) will be presented. The method of cumulant will give access to the $\mathrm{J}\mathrm{/}\psi$ flow fluctuations at forward rapidity. Alongside the new flow measurements of $\mathrm{J}\mathrm{/}\psi$, new results of $\mathrm{{\rm Y}}(1S)$ flow measurement at forward rapidity in ALICE Run 3 will be presented as well with comparison to model calculations.
