We look into the newly observed state from the molecular perspective in which the resonance is generated from the
,
and
channels. We find that this picture provides a natural explanation of the properties of the
state. We stress that the molecular nature of the resonance is revealed with a large coupling of the
to the
channel, that can be observed in the
decay which is incorporated automatically in our chiral unitary approach via the use of the spectral function of
in the evaluation of the
loop function.
