Option to hide the Doorbell Automation button
Hi,

In the recent update [v2.2.0](https://github.com/Brandawg93/homebridge-nest-cam/releases/tag/v2.2.0), a new button is added if the user has a Nest Hello doorbell. It's unconfigured by default, we can add actions to that button.

But the problem is that I don't know what I can do with that button, and I can't hide it if I don't need it.

I tried to use  it for turning on/off the video streaming, but it doesn't work well (and I have to use Nest app to reset the streaming).

So could you add an option to hide that button? I've disabled most of the features except audio, but the button is still there.

Thanks!
