A rule for a category

Hello!
I created a rule to only for a category ‘kvartiri’ unfortunately it is not working, the item is not seen anywhere((

add_filter( ‘if_menu_conditions’, ‘my_new_menu_conditions’ );

function my_new_menu_conditions( $conditions ) {
$conditions[] = array(
‘name’ => ‘Kvartiri’, // name of the condition
‘condition’ => function($item) { // callback – must return TRUE or FALSE
return is_category( ‘kvartiri’ );
}
);

return $conditions;
}
