Describe the problem you'd like to have solved

In v3 I can implement SessionStore. In v4 the new SessionDataStore is not exposed as a type, so that I cannot use this in implements.

Describe the ideal solution

export SessionDataStore interface.

Alternatives and current workarounds

Workaround:

type SessionStore = NonNullable<
  NonNullable<ConstructorParameters<typeof Auth0Client>[0]>['sessionStore']
>;
type SessionStorePayload = Parameters<SessionStore['set']>[1];
