Lightning component with checkboxes to update 2 seperate button Component

Hello Guys

I need a small Help

I am working on a Education project, I have four custom objects, Student__c, Class__c, course__c,Attandence__c
The first part is working fine,  in a class related list(Snapshot 1)  when I click on Update Attendance, a check box is checked in a student object (Snapshot 2) and it Is checked in child object Attendance object and Related Record Gets created (Snapshot 3)
Now I want to put another button called as Update Absentee, when I click this button, Checkbox should get updated in the Student object named (Check for Absentee) and related record should get created and it should not get updated in attendance custom object,

i have used 2 links for my requirement and developed my own code

Updateusingcheckbox.apex

public class UpdateUsingCheckboxC {
   
    @AuraEnabled
    public static List <Contact> fetchContact(string key) {
        system.debug('classname'+key);
        Class__c cls = [select id,Courses__r.name from Class__c where id=:key];
        string classname = cls.Courses__r.name;
        system.debug('classname'+classname);
        return [SELECT Id, Name,Account.Name,FirstName,LastName,Check_for_Attendance__c FROM Contact where Check_for_Attendance__c=false AND Account.Name =:classname];
    }
   
    @AuraEnabled
    public static void updateRecord(List <String> lstRecordId,string key) {
        List<Contact> lstUpdate = new List<Contact>();
        List<Attendancess__c> listAttendnce = new List<Attendancess__c>();
        Class__c cls = [select id,Courses__r.name from Class__c where id=:key];
        for(Contact con : [SELECT Id,AccountId, Name,Phone,FirstName,LastName,Check_for_Attendance__c  FROM Contact WHERE Id IN : lstRecordId]){
            con.Check_for_Attendance__c = true;
            lstUpdate.add(con);  
            Attendancess__c attandenc = new Attendancess__c();
            attandenc.Class__c = cls.Id;
            attandenc.Student_Attended__c = true;
            attandenc.Name = con.Name;
            attandenc.Created_Date_Time__c = system.now();
            listAttendnce.add(attandenc);
            system.debug('listAttendnce'+listAttendnce);
        }
        if(lstUpdate.size() > 0){
            update lstUpdate;
        }
        if(listAttendnce.size() > 0){
            insert listAttendnce;
        }
    }
}
