Nuki opener and ELVOX ART 900-902

Hi, i have an ELVOX ART 900-902 intercom. After verified the compatibility with the opener on the official website, i buyed it. Now, i tried to install it, but the physical situation of my intercom is different from the image on the guide. Result: following on of the installation guide, it works only for 1 door and only if I open it from my phone (i have a bridge too).
What doesn’t work:

  1. i’m not able to open the second door (the one of the buiding, the first is on the backyard on the street);
  2. it doesn’t work work in “ring to open” mode, but only if I open it from my phone.
    I attach the pic of my intercom.
    Thanks for help
