Balcom WS 20 with Nuki Opener

I have this Intercom from Balcom, type WS 20 and Im trying to install nuki opener with it.

There was a discussion about this same topic in 07/2022, but it seems to have run stale…

So I’m trying to find an anwer here.

Obviously - the cable connections are fixed, but what I need to know is
“What make and model did you use (in the Nuki App) as the Intercom?
The WS 20 apparently does not exist…”

Thanks for your help!
