Phone number on Checkout Page can’t include Country Code

Hello! On our checkout page the phone number field must NOT include country code. When the Phone field is filled-in on the Email Popup by the user, then the Abandoned Cart plugin automatically fill-in the phone number on Checkout page, including the country code. Can we exclude country code, please?

On our Checkout page we use a mask for Brazilian phone numbers, so it is not possible at all to enter the country code.

Thank you in advance!
