Stripe - how to create a customer with an account email AND a billing email?

For creating a customer in Stripe I use this:

await stripe.customers.create({
  description: 'My First Test Customer (created for API docs)',
  email: 'example@example.com',
  name: 'John',
  phone: "1234567",
});

But it creates me a customer with:

Account details:
example@example.com
Billing emails:
example@example.com

I want to send another email address to Stripe API and save it to the billing emails (instead the first one).

What do I need to send to Stripe API when creating a customer for setting one email as the account email and one for the billing email?
