RBS40 Orbi Voice (OV) Alexa implementation i.e. Ring Doorbell skill

I have just installed Ring Doorbell Pro. Once I got this working I install Alexa Ring skill and tried to get notification working on OV. Unfortunately with no luck. The same is with answering call - Alexa says that my device doesn't support that.

So, dear Netgear, could you drop any hints about Alexa implementation on Orbi Voice. This is so frustrating when you read that sth is working with Alexa and in fact it doesn't on Orbi Voice. Please make it clear.
