Integration of Iliadbox fiber router

I’m trying to integrate my new IliadBox fiber router. I understand it is a Freebox V8 router, but using the freebox integration does not work. Here i attach the api_version.json I got from the router (uid xxxxx-ed). Any hint? Thank you

{
  "box_model_name":"iliadbox (r1)",
  "api_base_url":"\/api\/",
  "https_port":49829,
  "device_name":"iliadbox Server",
  "https_available":true,
  "box_model":"ibxgw8-r1",
  "api_domain":"cybhjtsw.ibxos.it",
  "uid":"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "api_version":"8.5",
  "device_type":"FreeboxServer8,1"
}
