The latter is described by taking into account the fact that there are predictions for a hidden-charm state with strangeness that couples to $J/\\psi\\Lambda$. By using the coupling of the resonance to $J/\\psi\\Lambda$ from these predictions we show that a neat peak can be observed in the $J/\\psi\\Lambda$ invariant mass distribution, rather stable under changes of unknown magnitudes.
