If the new message has an older (lower) number, you can safely ignore it.

### Examples


```javascript
import { addOns } from '@wix/bookings';

addOns.onAddOnUpdated((event) => {
    // handle your event here
});

```javascript
import { createClient, AppStrategy } from '@wix/sdk';
import { addOns } from '@wix/bookings';

const wixClient = createClient({
  auth: AppStrategy({
    appId: 'MY-APP-ID',
    publicKey: 'YOUR_APP_PUBLIC_KEY',
  }),
  modules: {
      addOns,
