### Examples

### sendUserMessageStreamed
```javascript
import { interactiveFormSessions } from '@wix/forms';

async function sendUserMessageStreamed(interactiveFormSessionId,options) {
  const response = await interactiveFormSessions.sendUserMessageStreamed(interactiveFormSessionId,options);
};
```

### sendUserMessageStreamed (with elevated permissions)
```javascript
import { interactiveFormSessions } from '@wix/forms';
import { auth } from '@wix/essentials';

async function mySendUserMessageStreamedMethod(interactiveFormSessionId,options) {
  const elevatedSendUserMessageStreamed = auth.elevate(interactiveFormSessions.sendUserMessageStreamed);
  const response = await elevatedSendUserMessageStreamed(interactiveFormSessionId,options);
}
```

### sendUserMessageStreamed (self-hosted)
Self-hosted SDK calls require you to [create a client](https://dev.wix.com/docs/sdk/articles/work-with-the-sdk/about-the-wix-client.md).

```javascript
import { createClient } from '@wix/sdk';
import { interactiveFormSessions } from '@wix/forms';
// Import the auth strategy for the relevant access type
// Import the relevant host module if needed

const myWixClient = createClient ({
  modules: { interactiveFormSessions },
  // Include the auth strategy and host as relevant
});


async function sendUserMessageStreamed(interactiveFormSessionId,options) {
  const response = await myWixClient.interactiveFormSessions.sendUserMessageStreamed(interactiveFormSessionId,options);
};
```
