Firebase 10.8.0 TOTP多因素认证注册时出现TypeError问题

我在使用Firebase 10.8.0版本为Web应用添加TOTP多因素认证功能时，遵循官方文档的用户注册步骤操作：

• 已成功生成TOTP密钥并通过二维码展示给用户，方便导入至认证应用（对应文档步骤1-4）
• 后续提示用户输入认证应用的确认码，执行以下代码完成MFA注册（对应文档步骤5）：

const auth = getAuth().currentUser;
const multiFactorAssertion =
  TotpMultiFactorGenerator.assertionForEnrollment(
    totpSecret,
    verificationCode
  );

multiFactor(user)
  .enroll(multiFactorAssertion, "mfa_totp")
  .then((res) => {
     // Success
     console.log(res);
  })
  .catch((error) => {
     // Error
    console.log(error);
  });

执行时出现如下错误：

TypeError: this.secret._makeTotpVerificationInfo is not a function
    at TotpMultiFactorAssertionImpl._callee97$ (index-bea2a320.js:18548:1)
    at tryCatch (regeneratorRuntime.js:45:1)

    at MultiFactorUserImpl._callee54$ (index-bea2a320.js:12161:1)

    at Generator.next (regeneratorRuntime.js:74:1)
    at asyncGeneratorStep (asyncToGenerator.js:3:1)
    at _next (asyncToGenerator.js:22:1)

最初怀疑是包内Bug，后排查发现问题所在：

更新：问题已解决
生成multiFactorAssertion时，错误使用了totpSecret.secretKey作为参数，正确做法是直接传入totpSecret本身。
