typing.Bytes string will be removed in Python 3.14

[mxmlnkn]

I was trying to use this module in Python 3.14.0-alpha.0, and encountered this error:

Traceback:

E   ImportError: cannot import name 'ByteString' from 'typing' (/opt/hostedtoolcache/Python/3.14.0-alpha.0/x64/lib/python3.14/typing.py)

Looking at the changelog, it seems that typing.ByteString has been removed.
