Looks good. However, in designs we show the country flag of entered phone number. I think doing phone as variant would work better, and based on that we can render the country flag. Checkout Polymesh UI, we were using a package for phone numbers that showed flag out of box, and hopefully just do <Component as={isAmount ? NumberInput : isPhone ? PhoneInput : 'input'} />
