We are trying to register at the Peppol network following the official odoo 17 documentation. We get an validation error due to our luxembourgish phone number (+352....).

"Please enter the telephone number in the correct international format.

For example: +32123456789, where +32 is the country code.

Currently only European countries are supported."

+352 is the official country code for Luxembourg and as far as we know, should Luxembourg still be considered as an european country.

How could we get rid of this error, to register to the Peppol network?
