## Create an User

It's important to note that the concept of User only exists at the thread level, not at the Step level.

```python
import os
from literalai import LiteralClient
literal_client = LiteralClient(api_key=os.getenv("LITERAL_API_KEY"))

@literal_client.step()
def my_step(input_message):
    # some code, llm call, tool call, etc.
    answer = "answer"
    return answer

async def run(input_message):
    with literal_client.thread() as thread:
        literal_client.message(content=input_message, type="user_message", name="User")
        user = await literal_client.api.create_user(identifier="John Doe")
        # user = await literal_client.api.get_user(identifier="John Doe")
        thread.user = user
        answer = my_step(input_message)
        literal_client.message(content=answer, type="assistant_message", name="Assistant")
    return answer
```
