Self-deleting class in Python

EDIT: Disclaimer - I don't mean deletion in the sense that applies to languages that aren't memory-managed (e.g. free in C++). Deletion here is to be understood as the fact that the superclass doesn't have the subclass as one of its subclasses anymore after its been deleted.

In Python, you can delete a class (yes I do mean a class, not an instance) by doing the following:

class Super:
    ...
    
class DeleteMe(Super):
    ...

print(Super.__subclasses__())
# [<class '__main__.DeleteMe'>]

del DeleteMe
import gc
gc.collect() # Force a collection

print(Super.__subclasses__())
# []

I am trying to emulate this behaviour but I want the DeleteMe class to be able to destroy itself. Here is what I've tried:

class Super:
    ...
    
class DeleteMe(Super):
    def self_delete(self):
        print(self.__class__)
        # <class '__main__.DeleteMe'>, this looks right
        del self.__class__ # this fails
        import gc
        gc.collect()

print(Super.__subclasses__())
# [<class '__main__.DeleteMe'>]

DeleteMe().self_delete()

It fails with the following traceback:

Traceback (most recent call last):
  File "/Users/rayan/Desktop/test.py", line 10, in <module>
    DeleteMe().self_delete()
  File "/Users/rayan/Desktop/test.py", line 4, in self_delete
    del self.__class__
TypeError: can't delete __class__ attribute

How can I achieve this self-destructing behaviour?

Note: not a duplicate of How to remove classes from __subclasses__?, that question covers the first case where the deletion happens outside of the class
