Form Block - Add Country Code Select Option With Flag

It would be great if a user is given the option to select the country code in front of the telephone number or in the same field as the telephone number with a flag. So it eliminates the problem of adding +1 in front of the telephone field. For inspiration contact from 7 already has a plugin for this. Her it is – https://wordpress.org/plugins/country-phone-field-contact-form-7/ By doing so we can eliminate the need for two different fields by combining the country code select field in the telephone number. Used for businesses that capture international clients and have limited space in designing the form.
