Help for integrating two sketch together

Hello guys. Both of these sketch are compiling just fine. I want to integrate the clutch sketch into the steering wheel sketch but I am not sure where to put it so I keep getting errors.

I am sure it is not that complicated but I've tried many ways and I get a new error each time. can someone point me in the right direction please.

I want to put this one:

#include <Joystick.h>

// Create Joystick
Joystick_ Joystick;

// Variable

int clutch = A1; 


int clutchValue = 0;
int clutchValuebyte1 = 0;
int clutchValuebyte2 = 0;


// init joystick libary
void setup() {
  Joystick.begin();
}

void loop() {
  

  delay(1); 

  // Clutch
  clutchValue = analogRead(clutch);
  if (clutchValue >= 1) {
    clutchValuebyte1 = clutchValue / 4;
    clutchValuebyte2 = clutchValuebyte1 - 127;
  
   }
   }

into this steering wheel sketch:

#include <Keypad.h>
#include <Joystick.h>

#define ENABLE_PULLUPS
#define NUMROTARIES 4
#define NUMBUTTONS 24

Can anyone help me with that please.

See how to merge two sketches

Thank you very much guys. Stay safe as well.

-If- someone was to help.. How would they be able to test to see if their solution worked?
