Missing Origin in requests Headers when making http call via HttpClient

I am working with Angular 18, Capacitor 6, Ionic 7.
My problem is that all http client call are missing the Origin requests header, which leads to a problem on my server side since i check the origin of the api call thanks to this header.
I don’t know if it’s an Angular or Capacitor problem, i would say it is Capacitor because i have a webapp working only with Angular 18 and the Origin is well present in request Headers.
Does someone could help me ?
Thanks in advance

Do you have Capacitor http plugin enabled?

yes i have, requests are well sent, it’s just my server side needs origin request header so it fails
