hey, i have a little problem maybe someone can help.  
I want to generate lets encrypt certs with `ansible.builtin.acme_certificate`  
which seems to work, but i need to place the dns records, for this i use `community.general.netcup_dns`

My problem now is the result from acme\_certicate

```auto
    challenge_data_dns:
      _acme-challenge.example.net:
        - BKA2g7FqDE
        - SiUKqRuYI
      _acme-challenge.home.example.net:
        - gbYWTwtx3
      _acme-challenge.lab.example.net:
        - bAkdltnD3
        - efL6bGiTXI

```

I need to run netcup\_dns now multiple, 5 times in this example.

```auto
key:value
 _acme-challenge.example.net : BKA2g7FqDE
 _acme-challenge.example.net: SiUKqRuYI
_acme-challenge.home.example.net : gbYWTwtx3
_acme-challenge.lab.example.net : bAkdltnD3
_acme-challenge.lab.example.net : efL6bGiTXI

```

But the question is how to do this, i need somehow to loop over the single values in the list oh each key.

the with\_subelements module does not fit, because i’m not really able to predict the names after \_acme-challenge.

i has this litte example

```auto
- name: example
  hosts: all
  gather_facts: false
  strategy: linear
  vars:
    challenge_data_dns:
      _acme-challenge.example.net:
        - BKA2g7FqDE
        - SiUKqRuYI
      _acme-challenge.home.example.net:
        - gbYWTwtx3
      _acme-challenge.lab.example.net:
        - bAkdltnD3
        - efL6bGiTXI
  tasks:
    - name: debug out 
      debug:
        msg: "{{item}}"
      loop: "{{ challenge_data_dns | dict2items }}"
    
``
```
