  We have studied the meson-baryon $S-$wave interaction, using coupled
channels, in the isoscalar hidden-charm strange sector and $J^P = 1/2^-,3/2^-$
and $5/2^-$. We impose constraints of heavy quark spin symmetry in the
interaction and obtain the non vanishing matrix elements from an extension of
the local hidden gauge approach to the charm sector. The ultraviolet
divergences are renormalized using the same meson-baryon-loops regulator
previously employed in the non-strange hidden charm sector, where a good
reproduction of the properties of the newly discovered pentaquark states is
obtained. We obtain five states of $1/2^-$, four of $3/2^-$ and one of $5/2^-$,
which could be compared in the near future with forthcoming LHCb experiments.
The $5/2^-$, three of the $3/2^-$ and another three of the $1/2^-$ resonances
are originated from isoscalar $\bar D^{(*)}\Xi_c^\prime$ and $\bar
D^{(*)}\Xi_c^*$ interactions. They should be located just few MeV below the
corresponding thresholds (4446, 4513, 4588 and 4655 MeV), and would be
SU(3)-siblings of the isospin 1/2 $\bar D^{(*)} \Sigma_c^{(*)}$ quasi-bound
states previously found, and that provided a robust theoretical description of
the $P_c(4440)$, $P_c(4457)$ and $P_c(4312)$ LHCb exotic states. The another
two $1/2^-$ and $3/2^-$ states obtained in this work are result of the $\bar
D^{(*)}\Xi_c-D^{(*)}_s\Lambda_c$ coupled-channels isoscalar interaction, are
significantly broader than the others, with widths of the order of 15 MeV,
being $\bar D^{(*)}_s\Lambda_c$ the dominant decay channel.
