Is it possible to register_function with class instance method ?

[wudong]

I am trying to register function to LLM using autogen.register_function with some methods from a instance of a class:

    autogen.register_function(
        data.add_instrument,
        caller=assistant,
        executor=tools_executor,
        name="add_instrument",
        description="Add instrument with name and Id"
    )

but got exception:
File ".\repo\ai\eq-agbot\venv\Lib\site-packages\autogen\agentchat\conversable_agent.py", line 2706, in _decorator
func._name = name
^^^^^^^^^^
AttributeError: 'method' object has no attribute '_name'

Is this possible to register function in this way?
