Iphone 13 WiFi Calling on Orange France network

I have recently started using my new Iphone 13, I have however run into problems.

Facts:

Iphone 13 bought in USA

SW: IOS 15.2

Primary SIM: Orange Esim

Secondary SIM: Ice Norway

Orange subscription postpaid

Problem:

I cannot activate WiFi calling.

Orange latest explanation is that if the phone is not bought in France you cannot use WiFi calling on their network.

This is a limitation set by Apple not by Orange (according to them).

Has anyone had similar problems?
