The pentaquark states, $P_{c}(4312)$, $P_{c}(4440)$ and $P_{c}(4457)$, could be nicely arranged into a multiplet of seven molecules $\bar{D}^{(\ast)}\Sigma_{c}^{(\ast)}$ dictated by heavy quark spin symmetry. However, the spins $P_c(4440)$ $P_c(4457)$ are not yet fully determined. In this work we employ contact-range effective field theory to investigate $SU(3)$-flavor counterparts $\bar{D}^{(\ast)}\Sigma_{c}^{(\ast)}$, study possibility whether their discovery can help determine $P_c(4440)$. We find existence complete hidden charm strange $\bar{D}^{(\ast)}\Xi_{c}^{(\prime\ast)}$ irrespective $P_c(4457)$. On other hand, that although $\bar{D}^{(\ast)}\Xi_{c}$ also likely, depending on realization underlying dynamics, more useful $P_{c}(4457)$ tell how light interaction depends pair.
