When, in 2018, Matteo Salvini was minister and often didn't show up to his office, taking important calls from his mobile phone, the Italian Secret Service went pretty vocal (as much as a Secret Service can go vocal, anyway) against the practice for security reason. This time, we don't hear anything like that.

So either they decided that there's no hope in trying to secure the communications of Italian politicians, or they found out some way to secure the device to a degree they find satisfactory.
