We construct a separable Frobenius monoidal functor from (Vectω|ᴴ) to (Vectω) for any subgroup of which preserves braiding and ribbon structure. As an application, we classify rigid Frobenius algebras in (Vectω), recovering the classification of étale algebras in these categories by Davydov-Simmon...
