Doorbell accessory not being recognized in Home app
**Description**
I've been working on restoring homekit support to Arlo and started with doorbells. I've just been trying to get the doorbell alert working, however it seems in HOOBS that the accessory does not register properly. When I view the accessory in the Home app it shows greyed out and mentions that it's unsupported. Would love some eyes on this. 

Additionally, I've tested locally with homebridge@1.6.0 and homebridge-config-ui-x@4.50.2 and it appears to be working there.

**Plugin name**

**Additional context**
It registers the accessory, however it dosen't look like it's being recognized as a doorbell. Arlo sends the doorbell event through their basestation (aka hub), which is why the name is what it is. Otherwise the accessory has been configured as a Doorbell.

Here's the accessory configuration. I've masked any uuids. 
```json

And the accessory code for homebridge registration.
```ts
constructor(platform: ArloPlatform, accessory: PlatformAccessory) {
	this.arlo = platform.arlo
	this.log = platform.log;
	this.platform = platform;
	this.accessory = accessory;

	this.device = this.accessory.context.device as DEVICE_RESPONSE;

	this.accessory.getService(this.platform.Service.AccessoryInformation)!
	  .setCharacteristic(this.platform.Characteristic.Manufacturer, "Arlo")
	  .setCharacteristic(this.platform.Characteristic.Model, this.device.properties.modelId)
	  .setCharacteristic(this.platform.Characteristic.SerialNumber, this.device.deviceId);

	// Get the Doorbell service if it exists, otherwise create a new service.
	// Multiple services can be created for each accessory.
	this.service =
	  this.accessory.getService(this.platform.Service.Doorbell) ||
	  this.accessory.addService(this.platform.Service.Doorbell);

	// Sets the service name, this is what is displayed as the default name on the Home app.
	this.service.setCharacteristic(this.platform.Characteristic.Name, DisplayName(this.device));

	// Each service must implement at-minimum the "required characteristics" for the given service type
	// see https://developers.homebridge.io/#/service/Doorbell

	// add characteristic ProgrammableSwitchEvent
	this.service
	  .getCharacteristic(this.platform.Characteristic.ProgrammableSwitchEvent)
	  .onGet(() => null);

	this.service.setPrimaryService(true);
}
