No Xfinity integration with Alexa

I have the doorbell camera. On the Xfinity app it says I can link them to my Alexa devices via the Xfinity skill. However when you click the link or even search in Alexa there is no such skill. Is the integration no longer available? I currently have no doorbell chime so I never know when my bell is rang. It only shows on my phone because I have the app.
