It has recently been argued by Gaberdiel, Gopakumar et al. that type IIB string theory on $AdS_3 \times S^3 \times \mathbb{T}^4$ in the tensionless limit is exactly dual to the symmetric orbifold CFT $\text{Sym}^N(\mathbb{T}^4)$ in the large $N$ limit. One fascinating feature of this duality is that it is rendered manifest by a localisation of the physical correlators of tensionless strings to points in moduli space where a covering map exists, mapping the worldsheet to the boundary. In this talk, I will present my own argument for this localisation and demonstrate that it arises from the presence of a particular weight 3 gauge symmetry in the theory. This will allow us to extend the results in the literature to show that the localisation holds even for correlators containing non-highest weight states.
