spotipy: TypeError in oauth2

In file spotipy/oauth2.py in Class SpotifyAuthBase method __del__. Both arguments were of different types.

File "C:\Storage\Python Programs\project_vid_ed\.vEnv\lib\site-packages\spotipy\oauth2.py", line 156, in __del__
TypeError: isinstance() arg 2 must be a type, a tuple of types, or a union

Before the code was:

def __del__(self):
        """Make sure the connection (pool) gets closed"""
        if isinstance(self._session,requests.Session):
            self._session.close()

After fixing:

def __del__(self):
        """Make sure the connection (pool) gets closed"""
        # print(type(self._session))
        if isinstance(type(self._session),type(requests.Session)):
            self._session.close()

• OS: Windows 11
