I see in QtWebEngineCoremod.sip, there is import statement for QtWebChannelmod.sip

%Module(name=PyQt6.QtWebEngineCore, keyword_arguments="Optional", use_limited_api=True)

%Import QtCore/QtCoremod.sip
%Import QtGui/QtGuimod.sip
%Import QtNetwork/QtNetworkmod.sip
%Import QtWebChannel/QtWebChannelmod.sip

i think the issue seems due to darwin's version of PyQt6 are missing QHWebChannel.abi3.so in /nix/store/pba0k9dzk0l20wm8hn0wgqrii27c58l6-python3.12-pyqt6-6.8.0/lib/python3.12/site-packages/PyQt6 and QtWebChannel is missing site-packages/PyQt6/bindings

Steps to reproduce

nix build "nixpkgs#python312Packages.pyqt6-webengine"

Expected behaviour

package install correctly
