## Usage

To use the package, import the necessary functions in your TypeScript or JavaScript file:

```typescript
import {
  initUltronAI,
  sendMessageContent,
  sendSubmitEvent,
  sendAudioMessage,
  setupMessageListener,
  sendAudioUrlMessage,
} from "ultronai";
```

### Initializing Ultron AI

To initialize the Ultron AI, call the `initUltronAI` function with the ID of the div where the iframe should be embedded, the link to the iframe content, and the ID of the loading element:

```typescript
const sessionId = "created_with_ultron_api"; // please refer docs.ultronai.me
initUltronAI(
  "metabrix-labs",
  `https://app.ultronai.me/chat/?avatarId=xxxx&sessionId=${sessionId}`,
  "metabrix-loader"
);
```

### Sending Messages

You can send messages to the iframe using the provided functions:

```typescript
const iframe = document.getElementById("metabrix-labs").querySelector("iframe");

// Send a text message
sendMessageContent(
  iframe,
  "Hello, Ultron!",
  true,
  false,
  "https://app.ultronai.me"
);

// Send a submit event
sendSubmitEvent(iframe, "https://app.ultronai.me");

// Send an audio URL message
sendAudioUrlMessage(
  iframe,
  "https://example.com/audio.mp3",
  "https://app.ultronai.me"
);
```
