crossOriginEmbedderPolicy options are ignored when passed to helmet(config)

[yacc]

The options to crossOriginEmbedderPolicy are ignored when passed to helmet(config).
Passing the options through the middleware works fine.
See test bellow to reproduce.

Test

const request = require("supertest");
const express = require('express');
const helmet = require('helmet');

describe("Cross-Origin-Embedder-Policy through helmet()", function () {
  const app = express();
  const config = {
    crossOriginEmbedderPolicy: {
      policy: "credentialless",
    }
  };

  app.use(
    helmet(config)
  );

  app.use("/ping", function (req, res) {
    res.send("ok");
  });

  it("should insert Cross-Origin-Embedder-Policy", function (done) {
    request(app).get("/ping").expect("Cross-Origin-Embedder-Policy", /credentialless/).expect(200, done);
  });

});

describe("Cross-Origin-Embedder-Policy standalone", function () {
  const app = express();
  const config = {
    crossOriginEmbedderPolicy: {
      policy: "credentialless",
    }
  };

  app.use(
    helmet.crossOriginEmbedderPolicy(config.crossOriginEmbedderPolicy)
  );

  app.use("/ping", function (req, res) {
    res.send("ok");
  });

  it("should insert Cross-Origin-Embedder-Policy", function (done) {
    request(app).get("/ping").expect("Cross-Origin-Embedder-Policy", /credentialless/).expect(200, done);
  });

});

Test results

crossOriginEmbedderPolicy does not take options. Remove the property to silence this warning.
