$builder->select('support_tickets.*', DB::raw('(SELECT max(created_at) as latest_created_at FROM ticket_activities WHERE support_tickets.id = ticket_activities.ticket_id GROUP BY ticket_id) as latest'))
->orderByRaw('CASE WHEN EXISTS (SELECT max(created_at) as latest_created_at FROM ticket_activities WHERE support_tickets.id = ticket_activities.ticket_id GROUP BY ticket_id) THEN support_tickets.created_at ELSE latest END DESC')
->paginate(Arr::get($setting, 'perPage', 40));
