Hi Harsh, 

I already saw that discussion. I don't know how to modify the code shared to meet our requiement. Thanks
Hii Archie 
Try Below Code
trigger taskTrigger on task ( after insert ) {
    set<Id> OwnerId = new set<Id>();
    Map < string, String > mapAccIdTasks = new Map < string, String >();
    CustomNotificationType notificationType = [SELECT Id FROM CustomNotificationType WHERE DeveloperName = 'Desktop'];
    for ( task oTask : ) {


    map<Id,user> userMap = new map<Id,user>([SELECT Id,UserRole FROM User WHERE Id In :OwnerId]);

    for ( task oTask : ) {

    	user oUser = userMap.get(oTask.ownerid);
    	if(oUser.userRole == 'Operations'){


         Messaging.CustomNotification notification = new Messaging.CustomNotification();
        Set < String > recipientsIds = new Set < String >();
        notification.setTitle( 'File Attached to your Account' );
        notification.setNotificationTypeId( notificationType.Id );
            notification.setBody( 'File Id is ' + oTask.Subject );
            notification.setTargetId( oTask.Id );
            recipientsIds.add( oTask.OwnerId );
            notification.send( recipientsIds );
