In The carbonyl bond ( CO ), the Carbon attached to O group is electrophilic in nature as the O atom has attracted the electrons towards itself due to electronegativity of O.
In first step, Nucleophile N3 - will attack the electrohilic C , which leads to the resonance of the electron Pair between C and O group.
In step 2, the lone pair of O will attack back and hence , removal of Cl- which is a good leaving group will take place.
Thus, the sequence of steps is
Nucleophilic attack, loss of leaving group.
