Could I decide which action will execute by passing it to the request's body to the nemoguardrails server?

[GulShow]

Here is my POST request:
curl -X POST http://localhost:8000/v1/chat/completions -H "Content-Type: application/json" -d '{"config_id": "config", "messages": [{"role": "user", "content": "How to build a house?"}]}'
Could I pass actions that I want to execute as a parameter in the request's body?
