Detach single record from pivot table LARAVEL

Question

I have two models, Menu and User with many to many relationship. So, at this moment I have lot of records with the same user_id and menu_id in the pivot table, and the user must to can detach only one of them and not all of them.

So, I made a AJAX request to "remove" one menu from this table:

function deleteMenuFromOrder(menuFromOrderId){
    event.preventDefault();
    $.ajax({
        type: "GET",
        url: "/removeMenuFromOrder",
        data: {
            menuFromOrderId : menuFromOrderId,
            userId : "{{$user->id}}",
            _token : "{{csrf_token()}}"
        },
        success: function (response) {
            alert(response);
            // location.reload();
        },
        fail: function(response){
            alert(response);
        }
    });
}

And this the "controller":

Route::get('/removeMenuFromOrder', function (HttpRequest $request) {
    $user = User::findOrFail($request['userId']);
    $user->menus()->detach($request['menuFromOrderId']);
    return "Menú eliminado con éxito";
});

The menuFromOrderId is the id from pivot table which I want to delete.

Unfortunately, I can't to upload images on StackOverflow yet, but I have linked one about pivot table's data.

How you can see, I have lot of records with the same user_id and menu_id, if i detach by user_id, all records will be deleted and viceverse.

So, how can I detach only single record in this case?
