Nested Query To set value

[yonatan555]

I have this json:
{
"otlp_agent_collectors": [
{
"interval_in_seconds": 2,
"name": "watch_dog",
"state": "disabled"
},
{
"interval_in_seconds": 2,
"name": "script",
"state": "disabled"
},
{
"interval_in_seconds": 2,
"name": "otlp_agent",
"state": "disabled"
},
{
"interval_in_seconds": 2,
"name": "mis",
"state": "disabled"
},
{
"interval_in_seconds": 2,
"name": "blades",
"state": "disabled"
},
{
"interval_in_seconds": 2,
"name": "deployment",
"state": "disabled"
},
{
"interval_in_seconds": 2,
"name": "mds",
"state": "disabled"
},
{
"interval_in_seconds": 2,
"name": "processes",
"state": "disabled"
}
],
"script_collector_settings": {
"metrics": []
}
}

and I want to set a value using this query:
set(otlp_agent_collectors[2].state, "enabeld")
but it didn't work, what can I change the value?

set(otlp_agent_collectors2.state, "enabeld")
This was tested too, and still didnt work
but when I tried to get the value using this function get(otlp_agent_collectors.2.state), I got the real value
Thanks
