How can I customize CSS for "International Telephone Picker" Widget?

i am currently using a widget that allows for the selection of the country code input ("International Telephone Picker") for telephone numbers in our jotform form. This info is vital because our clients come from all over the world. Different countries also have different numbers of digits in their telephone numbers, meaning a format mask will not work, forcing us to use the widget. It seems the widget doesn't have a native way to:

1) Leave the country code component blank before selection (setting requires a default country code selected). This means, sometimes people don't actually select the correct code and just use the default setting leading to wrong contact info.

If we fix that first issue, then:

2) the widget doesn't have a way to force the manual selection of a country code. Some people are adding their country code into the phone input field instead of using the country code selector, creating wrong numbers. Is there any way we can prevent these issues using Custom CSS?
