use corejs Reflect metadata in typescript

[2239559319]

I try to use reflect metadata in ts and corejs as polyfill, but there will be a type error: "Property'defineMetadata' does not exist on type'typeof Reflect'". How should I solve this problem

How do you use core-js?

import 'core-js/proposals/reflect-metadata'; In the entry file

core-js does not contain types definitions, #568, you could try to use something like https://www.npmjs.com/package/@types/core-js, however, it's outdated.
