+ *        so the countries in which the state field is required by WC, and not provided by the browser are not supported.
+ *    3. Chrome does not provide a zip/postal code field for 60 out of the 249 countries WC supports. Only for 5 countries
+ *        the zip code field is missing while the state field is present: BS (Bahamas), PA (Panama), SC (Seychelles),
+ *        SR (Suriname), TV (Tuvalu). Several other countries provide an optional zip code field.
+ *    4. WC expects it, but there's no city field in the Payment Request API for the following:
+ *        JP (Japan), MO (Macao), TN (Tunisia), KY (Cayman Islands), GI (Gibraltar).
+ *    5. The following countries are not listed in WC:
