[Bug]: Activity Zone issues
### Describe the bug

Hi

I finally managed to notifications via HomeKit yesterday after changing the codec to h264_omx because I kept getting errors with default one (error 403). 
Now I get too many.
I subscribed to Nest Aware and setup 2 Activity Zones on Nest App. 
I went to the plugin config and could see the two zones exactly as I made them in Nest. Now I don't get any notifications via Home app but I do in Nest App.
I have checked on my iOS device and notifications are enabled. Any help will be great

Node.js Version v14.17.4
Npm Version v7.20.3

I ran npm upgrade -g homebridge homebridge-nest-cam (as sudo) and update to 8.1 I think

### Debug Output

I couldn't figure out how to do this, apologies.

Here is my config.json (minus key)
 "options": {
        "ffmpegCodec": "h264_omx",
        "streamQuality": 1,
        "alertCheckRate": 2,
        "alertCooldownRate": 72,
        "alertTypes": [
            "Zone - The zone",
            "Motion"
        ],
        "importantOnly": false,
        "motionDetection": true,
        "streamingSwitch": false,
        "announcementsSwitch": false,
        "audioSwitch": false,
        "fieldTest": false
    },
    "platform": "Nest-cam",
    "_bridge": {
        "username": "0E:65:67:9D:B8:E6",
        "port": 32459
    }
}
