validateRequest session.fresh not mentioned in new docs

[bdrtsky]

Migrating from lucia, but old examples used session.fresh in validateRequest function

export const validateRequest = cache(
  async (): Promise<
    { user: User; session: Session } | { user: null; session: null }
  > => {
    const { get, set } = await cookies()

    const sessionId = get("session")?.value ?? null
    if (!sessionId) {
      return {
        user: null,
        session: null,
      }
    }

    const result = await validateSession(sessionId)

    try {
      if (result.session && result.session.fresh) {
        const sessionCookie = lucia.createSessionCookie(result.session.id)
        set(sessionCookie.name, sessionCookie.value, sessionCookie.attributes)
      }
      if (!result.session) {
        const sessionCookie = lucia.createBlankSessionCookie()
        set(sessionCookie.name, sessionCookie.value, sessionCookie.attributes)
      }
    } catch {}
    return result
  },
)

I believe fresh is what lucia managed internally, now we need to do this ourselves but it is not mentioned anywhere
