Is there an API for Lightroom assets (not Classic)

Hello,

I have found this: https://developer.adobe.com/lightroom/lightroom-api-docs/api/#tag/Catalogs

But If I asked this API I get a response like this:

{
  "base": "https://lr.adobe.io/v2/",
  "id": "0c1b1a9b4a4f420c9...",
  "type": "catalog",
  "created": "2019-11-05T20:57:14.445760Z",
  "updated": "2022-07-20T17:52:43.688069Z",
  "links": {},
  "payload": {
    "name": "pictor_photography-v11.lrcat {DAA67135-665E-4504-BA73-C93...}",
    "profiles": {
      "favorites": {}
    },
    "settings": {}

  },
  "subtype": "lightroom"
}

This seems to be my old Lightroom Classic catalog. I found the pictor_photography-v11.lrcat on my MacBook. What I need to access is the catalog using in Lightroom CC (the new one). The ctalog I am using on my iPad, iPhone and so on.

Is there an API to access it?

Thanks in advance

Thorsten
