Perhaps you can contact their support. I did that also to ask whether the webhooks would arrive on other cams also. Answer was that R&D was informed about my question. Perhaps if lots of users ask it, that they really will have a look at it. Don't know.
P.S. first yet get a completely useless chatbot and then you need to type "type to a human"..
Meanwhile I have abandonned that way of working. I now capture the RTSP streams of ALL my cameras via Frigate (see this discussion), also for my Reolink video doorbell. That way I have recordings, snapshot images, motion detection, ... All my cams - inclusive the doorbell - now work in the same way. Very straightforward and stable architecture that way...
Then you will have to wait a long time, because that will never happen. I developed that node and made the source code public, but seems nearly nobody from this community has been interested over many years to help improving it. I don't have time to keep doing it all on my own, so case closed for me...
I saw above that you are looking for an alternative non-beta onvif node. If that should exist, I would really start wondering why that developer started from scratch again instead of simply doing a small pull request to help me improving my node...
