Idea

The concept of line n-bundle in complex analytic geometry, classified by maps into the $n$ -fold delooping $\mathbf{B}^n \mathbb{G}_m$ of the multiplicative group.

for $n = 0$ these are holomorphic functions classified by the group of units;
for $n= 1$ these are holomorphic line bundles, classified by Picard group, modulated by Picard stack;
for $n =2$ these are holomorphic line 2-bundles, classified by Brauer group, modulated by Brauer stack
