Ratios of $V^0$-triggered yields to charged-hadron triggered (h$-$h) ones, ${{Y}^{\mathrm{K^0_S}-\mathrm{h}}_{\Delta\varphi}}/{{Y}^{\mathrm{h-h}}_{\Delta\varphi}}$ (square points) and ${{Y}^{(\Lambda+\overline{\Lambda})-\mathrm{h}}_{\Delta\varphi}}/{{Y}^{\mathrm{h-h}}_{\Delta\varphi}}$ (circle points), for Pb$-$Pb (top panels) and pp (bottom panels) collisions in near side (left) and away side (right).
