How to use the webcrypto-core.AesGcmProvider function in webcrypto-core

import * as core from "webcrypto-core";
import { Crypto } from "../../crypto";
import { CryptoKey } from "../../key";
import { AesCrypto } from "./crypto";

export class AesGcmProvider extends core.AesGcmProvider {

  constructor(public crypto: Crypto) {
    super();
  }

  public async onGenerateKey(algorithm: AesKeyGenParams, extractable: boolean, keyUsages: KeyUsage[]): Promise {

        length: algorithm.length,
      },
      extractable,
      keyUsages);

    return key;
