### User function

The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).

- When used as an Input, the component only impacts the input signature of the user function.
- When used as an output, the component only impacts the return signature of the user function.

The code snippet below is accurate in cases where the component is used as both an input and an output.

- **As input:** Is passed, passes URL value as a {str} into the function.
- **As output:** Should return, expects a URL {str} to display in browser.

 ```python
def predict(
    value: str | None
) -> str | None:
    return value
