Py-KMS on Python Version 3.10 not working

Hello

I want to use py-kms for my homelab test but cannot start the service

here step by step what i have done

• Setup fresh winserver2019 std edition Evaluation (with desktop experience environment)
• Installed latest python (3.10.0) on C:\Program Files\Python310\ (for all users and with PATH Environment)
• installed with pip the dependencies mentioned at https://py-kms.readthedocs.io/en/latest/Getting Started.html#dependencies

py pip install tzlocal pysqlite3

• Unzipped py-kms-master.zip at C:\KMS\
• checking if python works correctly : OK

c:\KMS\py-kms>py
Python 3.10.0 (tags/v3.10.0:b494f59, Oct  4 2021, 19:00:18) [MSC v.1929 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()

• try to start pykms_Server.py and get an error

c:\KMS\py-kms>py pykms_Server.py
Traceback (most recent call last):
  File "c:\KMS\py-kms\pykms_Server.py", line 27, in <module>
    from Etrigan import Etrigan, Etrigan_parser, Etrigan_check, Etrigan_job

    from collections import Sequence
ImportError: cannot import name 'Sequence' from 'collections' (C:\Program Files\Python310\lib\collections\__init__.py)

c:\KMS\py-kms>

I would like to get some help to know if i missed one step

thanks you in advance
