/\+?\d{2}[\s-]?\d{3}[\s-]?\d{2}[\s-]?\d{2}/

This regex pattern matches any Polish phone number that starts with a plus sign (+) followed by two digits, followed by either a whitespace or hyphen character, followed by three digits, followed by either a whitespace or hyphen character, followed by two digits, followed by either a whitespace or hyphen character, and finally two digits.
