The SymTFTs that we consider are (3+1)d Dijkgraaf-Witten (DW) theories for finite groups $G$, whose gapped boundaries realize all so-called ``All Bosonic type\" fusion 2-category symmetries. In arXiv:2408.05266 we provided the general framework and studied the case where $G$ is an abelian group. In this work we focus on the case of non-Abelian $G$. Gapped boundary conditions play a central role in the SymTFT construction of symmetric gapped phases.
