In this mechanism, the $\\Lambda^+_c$ decays into the $K^* \\Sigma^*(1385)$, the $\\Sigma^*(1385)$ decays into the $\\pi^0 \\Sigma$ (or $\\Lambda$), and then the $K^* \\Sigma$ (or $\\Lambda$) interact to produce the $\\phi p$ in the final state. This mechanism produces a peak structure around $2020$ MeV. In addition, the possibility that there is a hidden-strange pentaquark-like state is also considered by taking into account the final state interactions of $K^* \\Lambda$, $K^* \\Sigma$, and $\\phi p$.
