Compiling Freenove_4WD_Car_WiFi.cpp - error -'class WiFiClass' has no member named 'mode'

[raspberrypieman]

I am using Arduino 1.8.11 on WIndows/10 and am compiling Freenove_4WD "Ordinary_wheels" 06.2_Multi_Functional_Car.ino.
The compilation fails on the Freenove_4WD_Car_WiFi.cpp module, on
line 24: WiFi.mode(WIFI_AP_STA);
'class WiFiClass' has no member named 'mode'

I presume that Arduino is not picking up the correct version of the Wifi library ?
Can you please help me locate the correct library, so that I can compile this application, without error?

The target is a Raspberry Pi PicoW. Prior to compiling, I updated the Libraries and the Board Manager.
