How can I deliver a py::class to the Python function that receiving a cls arg from C++ side?

[JoyChenNo1]

For some reasons, I have to use pybind to call Python third-party packages(such as python-docx) to deal with office documents from the C++ sides, while python-docx package need to accept a custom python class to deal with the custom xml node.
some thing like that:

from docx.oxml import register_element_cls

class CT_Anchor:
    @classmethod
    def func1(x, y):
          ...
          # this function define a custom xml node parsing rules.

# register self-defined calss to the docx.oxml package
# so that  can call docx.oxml package's other function to parse "wp:anchor" node.

register_element_cls("wp:anchor", CT_Anchor)

Is there possible for me to define a py::class from C++ side and deliver to python function like this?:

py::class_ <CT_Anchor> c(CT_Anchor);
c.def_property_static("func1", []{...});

py::module oxml  = py::module::import("docx.oxml");
oxml.attr("register_element_cls")("wp:anchor", c);
