I'm trying to use the Promise.allSettled API with TypeScript. Code here:

server.test.ts:

it('should partial success if QPS > 50', async () => {

  const requests: any[] = [];

  for (let i = 0; i < 51; i++) {

    requests.push(rp('http://localhost:3000/place'));

  }

  await Promise.allSettled(requests);

  // ...

});

But TSC throws an error:

Property 'allSettled' does not exist on type 'PromiseConstructor'.ts(2339)

I already added these values to the lib option in tsconfig.json:

tsconfig.json:

{

  "compilerOptions": {

    /* Basic Options */

    "target": "ES2015" /* Specify ECMAScript target version: 'ES3' (default), 'ES5', 'ES2015', 'ES2016', 'ES2017','ES2018' or 'ESNEXT'. */,

    "module": "commonjs" /* Specify module code generation: 'none', 'commonjs', 'amd', 'system', 'umd', 'es2015', or 'ESNext'. */,

    "lib": [

      "ES2015",

      "ES2016",

      "ES2017",

      "ES2018",

      "ES2019",

      "ES2020",

      "ESNext"

    ] 

   // ...

}

TypeScript version: "typescript": "^3.7.3"

So, how can I solve this? I know I can use an alternative module, but I am curious about working with TypeScript natively.
