Ring intercom Integration with comelit 2608

Anyone achieve to make it works? as the menu has the instructions, i connected to my intercom.
It works with the second door, but not with the main access.

The bad point is that i cannot configure for the main access and if i configure only for my building, the intercom of the main access doesn’t work.

Any experience, clue or idea to test?

The error in the main door with its connected to the one of. my building
