Inspired by the recent observation of a new structure, $X(4014)$, in the process $\gamma \gamma \to \gamma \psi (2S)$, we evaluate the possibility of assigning $X(4014)$ as a $D^{*}{\overline{D}}^{*}$ molecular state with $I(J^{PC})=0(0^{++})$ by investigating the hidden charm decays of $X(4014)$. The partial widths of $J/\psi \omega$, ${\eta }_c\eta$ and ${\eta }_c{\eta }^{\prime }$ channels are evaluated to be about (0.41–5.00), (2.05–7.49) and (0.11–0.51) MeV, respectively. Considering the experimental observation and the present estimations, we proposed to search $X(4014)$ in the $\gamma \gamma \to J/\psi \omega$ process in Belle II.
