In the present work, we investigate the productions of 
in 
and 
decays, where is assigned as a 
molecular state. By using an effective Lagrangian approach, we evaluate the branching fractions of 
and 
via the triangle loop mechanism. The estimated branching fractions of and are of the order of 
and 
, respectively. The ratio of these two branching fractions is estimated to be about 4, which indicate that the 
may be a better process of searching and accessible for further experimental measurements of the Belle II and LHCb Collaborations.
