G4 Pro motion not supported in HomeKit
**Describe The Problem:**
My G4 Pro does not have the option to enable motion events under notifications, my G4 Doorbell does have that option.

**To Reproduce:**
Add the G4 Pro to Unifi Controller.

**Logs:**
The logs do not show any errors.

```

**Homebridge Configuration:**

If I enable `Enable.Motion.SmartDetect` does it disable `Enable.Motion.Sensor` ? 

```json
{
    "controllers": [
        {

        }
    ],
    "platform": "UniFi Protect"
}	
```
