Query: Non-Invertible Symmetries from Discrete Gauging and Completeness of the
  Spectrum   We study global 1- and $(d-2)$-form symmetries for gauge theories based on
disconnected gauge groups which include charge conjugation. For pure gauge
theories, the 1-form symmetries are shown to be non-invertible. In addition,
being the gauge groups disconnected, the theories automatically have a
$\mathbb{Z}_2$ global $(d-2)$-form symmetry. We propose String Theory
embeddings for gauge theories based on these groups. Remarkably, they all
automatically come with twist vortices which break the $(d-2)$-form global
symmetry. This is consistent with the conjectured absence of global symmetries
in Quantum Gravity.
