Abstract: Inspired by the recent observation of a new structure, $X(4014)$, in the process $\ensuremath{\gamma}\ensuremath{\gamma}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\psi}(2S)$, 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 $J/\ensuremath{\psi}\ensuremath{\omega}$, ${\ensuremath{\eta}}_{c}\ensuremath{\eta}$ and ${\ensuremath{\eta}}_{c}{\ensuremath{\eta}}^{\ensuremath{'}}$ 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 $\ensuremath{\gamma}\ensuremath{\gamma}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\omega}$ process in Belle II.
