bash – Centrify: install using script in macOS 10.15

We were used to install Centrify using a simple script launched from KACE:

sudo /usr/sbin/installer -pkg CentrifyDC-5.5.2-x86_64.pkg -target /

Starting from Catalina, it seems that the script installs Centrify (I can find files and folders in the hdd) but the entry in the System Preferences (that is the join assistant) does not appear and also checking in the file system I cannot find the correct application to launch it.
If I install Centrify using the same .pkg file but in the interactive way (with the GUI) everything works smoothly. Does anybody know why?
