Custom PyQt5 widgets Qt Designer

Question

I have been trying (without success) to get Custom PyQt5 widgets to show up in Qt Designer for a couple of days now.

Some information: Window, Python 3.9.1, Pyqt5.15.6, Qt Designer 5.11.1

I have downloaded the source code for PyQt5-5.15.6 here, and I am trying to run the example under: PyQt5-5.15.6\examples\designer\plugins

Qt Designer does launch, but no additional widgets appear in the menu. Under help > plugin information it says: "Failed to extract plugin meta data from 'C:/Program Files (x86)/Qt Designer/plugins/designer/pyqt5.dll". Could this be why the widget imports are not working as expected?

In Qt Designer there is a "Promote to..." feature to customize components. There you indicate the file and class respectively in "Header file" and "Promoted class name".

Here you see more information:
