### Examples

### updateSchema
```javascript
import { translationSchemas } from '@wix/multilingual';

async function updateSchema(_id,schema) {
  const response = await translationSchemas.updateSchema(_id,schema);
};
```

### updateSchema (with elevated permissions)
```javascript
import { translationSchemas } from '@wix/multilingual';
import { auth } from '@wix/essentials';

async function myUpdateSchemaMethod(_id,schema) {
  const elevatedUpdateSchema = auth.elevate(translationSchemas.updateSchema);
  const response = await elevatedUpdateSchema(_id,schema);
}
```

### updateSchema (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 { translationSchemas } from '@wix/multilingual';
// Import the auth strategy for the relevant access type
// Import the relevant host module if needed

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


async function updateSchema(_id,schema) {
  const response = await myWixClient.translationSchemas.updateSchema(_id,schema);
};
```
