Phone Number - Checkout - Freeform Entry Or Remove International Code

Hi

How do I remove the silly international code requirement for the phone number at checkout - or even better, just make it free form entry. I've read tons of pages on the forum and can't find a solution.

Its not even formatted correctly for UK phone numbers, even when the country code is added.

A not silly way is to search the docs also. Here: https://docs.cs-cart.com/latest/user_guide/users/customers/phone_validation.html?highlight=phone%20format
