How to validate country field in Address section?

Summary:

Hello everyone,

I'm trying to validate using autocomplete rules a country field in Address section during a Hire action.

Specifically, we need to show an error message if this field is null by clicking on Continue.

I tried to use Object Validation Rule type but the rule seems to work only when the field is filled.

for example by filling Country= Italy only then the other fields will appear and the rule will work (for example: If country is not equals to Italy then show an error)

This is the rule logic we did:

Can you help us to find a possible solution to this problem?
