Hello,
I need to integrate this situation to show a link depending on the order country

{% if billing_address.country_code == “FR” %}

Invoice European Union LINK
{% else %}
Invoice International None European Union LINK
{% endif %}

Is there any liquid code to choose the all the european countries ?
I Would like to know if it will work on a shipping confirmation email template ?

Thanks for your help everyone
