How to use the @vue/reactivity.lock function in @vue/reactivity

// the props proxy
  const { patchFlag } = instance.vnode
  if (
    propsProxy !== null &&
    (patchFlag === 0 || patchFlag & PatchFlags.FULL_PROPS)
  ) {
    const rawInitialProps = toRaw(propsProxy)
    for (const key in rawInitialProps) {
      if (!hasOwn(props, key)) {
        delete propsProxy[key]
      }
    }
  }

  // lock readonly
  lock()

  instance.props = props
  instance.attrs = options ? attrs || EMPTY_OBJ : props
}
