Our proof is an adaptation of the arguments of Langlands and Rapoport [LR87] of deriving the Kottwitz’s formula from their conjectural description of the set of mod-$p$ points of Shimura variety (Langlands–Rapoport conjecture), but replaces their Galois gerb theoretic arguments by more standard group-theoretic ones, using Kisin’s geometric work [Kis17].
