Undertaker Entering Arena - Isabelle coming to Animal Crossing: New Horizon after spending months in Smash

Okay I'm actually curious now; it's inevitable that Isabelle's gonna be in New Horizons because of her status as the most-popular character in the Animal Crossing series, but how will they implement her, given that New Horizons doesn't seem to be going for the same "you're the mayor" angle? Is she just gonna be chilling there on the island? Is she gonna be a literal advice animal? Is she gonna work there?
