ansible jinja2 seperate certain interfaces from list - ansible

Question

I'm new to jinja and ansible, and am still trying to wrap my head around how to work with them.
In my case, I'm trying to get a sublist of interface names, where I can execute a certain action on if the description key contains a certain value.
I tried things with an if map construction, but that did seem to work out.
Any suggestion how to do this?
I have the following
- hosts: Router1
gather_facts: false
connection: network_cli
tasks:
- name: get interfaces
arista.eos.eos_interfaces:
state: gathered
register: all_interfaces
- name: check debug
debug:
msg: "{{ all_interfaces.gathered }}"
- name: only configured by Ansible ports
set_fact:
interface: >
{% if 'Configured by Ansible' in all_interfaces.gathered|map(attribute='description')%}
{% endif %}
- name: check debug
debug:
msg: "{{ interface }}"
The list printed out (and which I try to use)
[
{
"description": "Router2",
"enabled": true,
"mode": "layer3",
"name": "Port-Channel1000"
},
{
"description": "Router2",
"enabled": true,
"name": "Ethernet1"
},
{
"description": "",
"enabled": true,
"name": "Ethernet2"
},
{
"description": "",
"enabled": true,
"name": "Ethernet3"
},
{
"description": "",
"enabled": true,
"name": "Ethernet4"
},
{
"description": "Configured by Ansible",
"enabled": false,
"name": "Ethernet5"
},
{
"description": "Configured by Ansible",
"enabled": false,
"name": "Ethernet6"
},
{
"enabled": true,
"name": "Ethernet7"
},
{
"enabled": true,
"name": "Ethernet8"
},
{
"enabled": true,
"name": "Loopback0"
},
{
"enabled": true,
"name": "Management0"
},
{
"enabled": true,
"name": "Management1"
}
]
