How to give a name to function arguments in C-API?

Hello.
I'm trying to solve this problem but still in pycharm, when i'm looking at my function argument
name i see only "*args" and "**kwargs" despite "labels_list" which i set while defining my function in
C++.
I can pass argument with keyword "labels_list" or without it, but i can't see this argument name
in function arguments list in PyCharm.

Here is my code:

static PyObject* encode_one_hot(PyObject* self, PyObject* args, PyObject* kwargs) {
 
    PyArrayObject* labels = NULL;
    PyArrayObject* one_hot;
 
    npy_intp dims[2];
 
    map<int, int> classes_map;
 
    int current_label;
    int labels_size;
 
    int new_numeration = 0;
 
    void* ptr;
 
    static char* kwlist[] = { (char*)"labels_list", NULL };
 
    if (!PyArg_ParseTupleAndKeywords(args, kwargs, "O", kwlist, &labels))
        return NULL;
 
 
    PyArray_Sort(labels, 0, NPY_QUICKSORT);
 
    labels_size = PyArray_SIZE(labels);
 
    for (int i = 0; i < labels_size; i++) {
        ptr = PyArray_GETPTR1(labels, i);
        current_label = PyLong_AsLong(PyArray_GETITEM(labels, ptr));
 
        if (classes_map.find(current_label) == classes_map.end()) {
            classes_map[current_label] = new_numeration;
            new_numeration++;
        }
    }
 
    dims[0] = labels_size;
    dims[1] = (int)classes_map.size();
 
    one_hot = (PyArrayObject*)PyArray_ZEROS(2, dims, NPY_INT, 0);
 
    for (int i = 0; i < labels_size; i++) {
        current_label = classes_map[PyLong_AsLong(PyArray_GETITEM(labels, PyArray_GETPTR1(labels, i)))];
        ptr = PyArray_GETPTR2(one_hot, i, current_label);
 
        PyArray_SETITEM(one_hot, ptr, PyLong_FromLong(1));
    }
     
    return PyArray_Return(one_hot);
}

I'll be very grateful for help :)
