How To Add Shipping Phone Number to the checkout page?

Hi!

For our shipping system they ask us for the shipping phone number.

It seems to me that it is a woocommerce field and it is not necessary to create a new one (If I enter Order details / Shipping I see the possibility of adding a phone). What is the recommended way to add it to the form?

Thanks!

PD: I've seen this, but maybe there's something already done in generatepress
