apex class to update Emailoptout checkbox directly if unsubscribe link is clicked, without Email popup

Hey guys,
i am new to the apex development, i am trying to design a apex code 
where it should directly update emailoptout checkbox in lead and contact when unsubscribe link is clicked

i know there is an app exchange app called "Unsubscribe opt-out", i tried copying and modifying that code, when email comes
from my instance to my personal gmail, and when i click on unsubscribe link, unsubscribe email popup comes and i need to send another
mail and then emailoptout checkbox gets updated
 
Global class unsubscribe implements Messaging.inboundEmailHandler{

Global Messaging.InboundEmailResult handleInboundEmail(Messaging.InboundEmail email, 
                            Messaging.InboundEnvelope env ) {

// Create an inboundEmailResult object for returning 
//the result of the Apex Email Service
Messaging.InboundEmailResult result = new Messaging.InboundEmailResult();
 
// Contact and Lead lists to hold all the updated records
List<Contact> lc = new List <contact>();
List<Lead> ll = new List <lead>();
 
// Convert the subject line to lower case, so I can match on lower case
String mySubject = email.subject.toLowerCase();
// String I am searching for in the subject line
String s = 'unsubscribe';
 
// Check variable to see if the word "unsubscribe" was found in the subject line 
Boolean unsubMe;
// Look for the unsubcribe word in the subject line, 
// if it is found return true, otherwise false is returned
unsubMe = mySubject.contains(s);
 
 // If unsubscribe is found in the subject line enter the if statement
 
 if (unsubMe == true) {
    
    try {
        
    // Lookup all contacts with a matching email address
        
     for (Contact c : [Select Id, Name, Email, HasOptedOutOfEmail
                        From Contact
