I want to select a specific key from the output/results array but I’m having difficulties, I’ve already checked this post but I was unable to adapt it to my playbook:

---
- hosts: '{{ site }}'
  gather_facts: false
  tasks:
  - name: Get Checkmk version
    community.windows.win_file_version:
     path: 'C:Program Files (x86)checkmkservicecheck_mk_agent.exe'
    register: file_version
  - debug:
     var: file_version

I want to select the output of “product_version” for example “2.2.0p7”.

TASK [debug] *******************************************************************
ok: [10.10.10.10] => {
    "file_version": {
        "changed": false,
        "failed": false,
        "win_file_version": {
            "file_build_part": "0",
            "file_major_part": "2",
            "file_minor_part": "1",
            "file_private_part": "0",
            "file_version": "2.1.0.0",
            "path": "C:\Program Files (x86)\checkmk\service\check_mk_agent.exe",
            "product_version": "2.2.0p7"
        }
    }
}
