Hi,  
According to: [Elastic Agent policies | Fleet and Elastic Agent Guide [8.16] | Elastic](https://www.elastic.co/guide/en/fleet/current/agent-policy.html#:~:text=To%20add%20a%20custom%20field,and%20scroll%20to%20Custom%20fields). I should be able to add custom field to agent policies.  
I simply don't have the option.  
If I try and add via an API request:

```auto
PUT kbn:/api/fleet/agent_policies/.....
{
  .
  .
  namespace: "blah",
  "custom_fields": {
    "test":"test"
  }
  .
}

```

I get "[request body.custom\_fields]: definition for this key is missing"  
Running self hosted 8.13.3 (freebie tier).

Any idea what I'm missing?

thanks

Steve
