Include Library in another library

How to include another library in a library?
I am using Edge Impulse for training ML, then upload the zip file in Arduino.
Then, i want to upload the data to Arduino IoT Cloud, using ArduinoIoTCloud library.
In the portenta_h7_microphone_continuous.ino sketch, i include these headers.

#include <trialaudio_inferencing.h>
#include <Arduino.h>
#include <ArduinoIoTCloud.h>
#include "arduino_secrets.h"
#include "thingProperties.h"

But I got these errors

 WiFiConnectionHandler ArduinoIoTPreferredConnection(SECRET_SSID, SECRET_PASS);

I am beginner in Arduino and have limited understanding on how the libraries work.

Remove that library as it clashes with ArduinoIoTCloud.

I guess this ("SECRET_SSID") is thought to be replaced by your actual SSID. Same applies to "SECRET_PASS".
