How to get all function calls from within a UFunction?

Hi,

I want to create a plugin where I need those function calls from every UFunction. Is there a way to retrieve those?
For instance if this class exists as blueprint I could traverse the blueprint graph. I assume that UEdGraphs are not getting extra generated/created from CPP classes.

I have searched the api for any useful function but I couldn’t found one.

Regards,
