Nuki Opener connection to a Bell System Bellisimo Intercom

Hi all, I am new here and wanted to see if anyone has tried to connect a Nuki Door Opener to Bell System that has CAT5 cabling and the intercom has video and audio capability. I have the Nuki Pro 3.0 and really want to add the Nuki Opener, but before buying wanted to see if it’s actually possible to connect. I have added some pictures of the handset and wiring. Thanks in advance for anyones help, and or guidance!
