VSC+PlatformIO: print f outputs not visible in Serial Monitor or Terminal

[Alberto77]

I'm new in IOT programing (so sorry for this simple question) and I'm using VSC+Platform IO and my device is ESP32 Dev.
I successfully started with the Arduino Framework and today I tried the ESP IDF, beginning with the "Hello World" example.
Unfortunately I don't see the outputs generated by the program.
The standard output in the Arduino Framework is the serial monitor ( using Serial.println(....) ).
In the ESP IDF example program printf(...) is used instead. Where in VSC/PIO can I see the outputs?
Many thanks in advance for advices.
