Futura Digital Intercom with Nuki Opener

Hi - I would like to ask for you kind help in installing the Opener.

I have a Futura Digital VDT-433 intercom.

I would like to connect to it to the Nuki Opener, but on the back I only saw two cables… Please see the pics attached.

Could anyone help or guide me through the process?

Many thanks,
P
