TypeError: unsupported operand type(s) for |: 'type' and 'NoneType'

Hello,

I'm tyring to run the fullscreen.py and the hidden.py examples, but I get stuck on this error:

Traceback (most recent call last):
  File "fullscreen.py", line 2, in <module>
    from textual_filedrop import FileDrop
  File "C:\Users\Rasmus\AppData\Local\Programs\Python\Python38\lib\site-packages\textual_filedrop\__init__.py", line 1, in <module>
    from ._filedrop import FileDrop

    class FileDrop(Widget, can_focus=True, can_focus_children=False):

    name: str | None = None,
TypeError: unsupported operand type(s) for |: 'type' and 'NoneType'

Example files are unmodified. OS is Windows 10, Python version string is:
Python 3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 23:11:46) [MSC v.1916 64 bit (AMD64)] on win32

Am I doing something wrong? I installed through pip, so any dependencies should have been taken care of.

Oh it is probably compatibility issue, I'll take a look when I get to the computer.
