CDK UserpoolClient refreshTokenValidity duration fails to synthesize correctly

In order to define the Cognito UserPool client, you can refer to the addClient function of the UserPool construct in CDK and then define the refreshTokenValidity duration to correctly synthesize the construct to the corresponding CloudFormation resource

const pool = new cognito.UserPool(this, 'Pool');
    const provider = new cognito.UserPoolIdentityProviderAmazon(this, 'Amazon', {
      userPool: pool,
      clientId: 'amzn-client-id',
      clientSecret: 'amzn-client-secret',
    });

const client = pool.addClient('app-client', {
      refreshTokenValidity: cdk.Duration.hours(12),
      idTokenValidity: cdk.Duration.hours(2),
      accessTokenValidity:cdk.Duration.hours(2),
      supportedIdentityProviders: [
        cognito.UserPoolClientIdentityProvider.AMAZON,
      ],
    });

client.node.addDependency(provider);
