Code completion not working for class methods

Code completion does not work for the example below both when "Auto Pop-up" is enabled or triggering using Ctrl+Space.

Is this a bug or does the TestComplete editor not support it at all? Any recommended IDE that will do this and work with TestComplete objects?

#tests.py

class A:
    def Greet(self):
        Log.Message("Hi from A.Greet")
        
        
def test1():
    x = A()
    x. #I want autocomplete to popup here
