[Python] How can I specify a tzinfo object as a Type Hint in Python?

Would you know what is the correct type to use when specifying datetime.now().astimezone().tzinfo?

I tried specifying the type of this datetime.now().astimezone().tzinfo Python (3.10.5) object using Type Hints in several ways (thus the libraries imported in the code below), but this far nothing works and I get error: Incompatible types in assignment (expression has type "tzinfo | None", variable has type "timezone") [assignment]. I already looked at other solutions in vain...

import nb_mypy
%load_ext nb_mypy
%reload_ext nb_mypy
%nb_mypy On
%nb_mypy DebugOff

import pytz
from datetime import datetime, timedelta, date, timezone
from dateutil.relativedelta import relativedelta
from typing import Generator, Any
from types import ModuleType
from pytz.tzinfo import DstTzInfo, StaticTzInfo

time_zn_in_graph: timezone = datetime.now().astimezone().tzinfo


I settled on timezone above because that's the type I get:

print(type(datetime.now().astimezone().tzinfo))

<class 'datetime.timezone'>

but I still get the error...
