You need to import persistence states this way:

import {
  getAuth,
  setPersistence,
  browserLocalPersistence,
  browserSessionPersistence,
  inMemoryPersistence
} from "firebase/auth";

const auth = getAuth()

await setPersistence(auth, browserLocalPersistence);

firebase.auth.Auth.Persistence.LOCAL browserLocalPersistence
firebase.auth.Auth.Persistence.SESSION browserSessionPersistence
firebase.auth.Auth.Persistence.NONE inMemoryPersistence
