Nuki Opener with Siedle BVPS 850

Hello,

has anyone out here been able to connect a Nuki Opener to the Siedle BVPS 850 Bus Intercom? It is not on the list of supported devices, so I am wondering if there might be another way to connect it. Attached some fotos of the Panel.

Many thanks in advance
Burkhard

It lets me only post one foto at a time, so here the other:
