# Pre-built UI Prefabs

We provide several UI options to display character and user's transcript out of the box that players can use with the Convai Plugin. You can use and customize these prefabs.

The ConvaiNPC and ConvaiGRPCAPI scripts look for GameObjects with Convai Chat UI Handler as a component, and send any transcripts to the script so that it can be displayed on screen.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.convai.com/api-docs/plugins-and-integrations/unity-plugin/utilities/convai-ui-prefabs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
