Hidden-charm pentaquark-like $P_{\psi s}^\Lambda(4459)^0$ and $P_{\psis}^\Lambda(4338)$ resonances are studied in a constituent quark model asmolecular meson-baryon structures. Such states are found in the$J^P(I)=\frac{1}{2}^-(0)$ channel with masses and widths compatible with theexperimental measurements in a coupled-channels calculation with all theparameters constrained from previous studies. Other candidates are explored inthe $J^P=\frac{1}{2}^-$, $\frac{3}{2}^-$ and $\frac{5}{2}^-$ channels in thecharm and bottom sectors, with isospins $0$ ($P_{\psi s}^\Lambda$ and$P_{\Upsilon s}^\Lambda$) and $1$ ($P_{\psi s}^\Sigma$ and $P_{\Upsilons}^\Sigma$). Additionally, the formalism is extended to study the $P_{\psiss}^N$ ($P_{\Upsilon ss}^N$) pentaquarks, where eight candidates are predictedas $\bar D_s \Xi_c$ molecules in $I=\frac{1}{2}$, with $J^P=\frac{1}{2}^-$,$\frac{3}{2}^-$ and $\frac{5}{2}^-$ for the charm sector and nine candidates as$B_s \Xi_b$ for the bottom one.
