No module named 'win32api' when importing win32com

I am trying to use Pyoxidizer to build a python program that tries to use the win32com module from pywin32. As soon as I try to `import win32com` I get the following error:

> No module named 'win32api'

Is this there a way to fix this problem?

Start by reproducing the `import win32com` failure in a PyOxidizer-built Python program on Windows, then inspect how PyOxidizer handles pywin32's `win32api` dependency. Done means the packaged program imports `win32com` without the reported missing-module error.
