There are two known reasons this plugin does not work.
As of macOS 10.15 (Catalina), apps need to explicitly allow Device Abstraction Layer (DAL) plugins to work by setting com.apple.security.cs.disable-library-validation in their Info.plist. For apps that don't set this key (e.g. Zoom and Slack), it's possible to manually add this key, then re-codesign the app. Take a look at issue #4 for details. Note that you'll need to redo this process every time the app is opened.
You can try to re-codesign the application to avoid this. Please be aware this could have security implications for the app. For example (for Zoom):
sudo codesign -f -s - /Applications/zoom.us.appIf that doesn't help, you can try to remove the signature of the Renderer. Please be aware this could also have security implications. For example Skype:
sudo codesign --remove-signature /Applications/Skype.app/Contents/Frameworks/Skype\ Helper\ \\(Renderer\\).appRecent versions of macOS seem to disallow DAL plugins for system apps (e.g. Safari, FaceTime, Photo Booth). More investigation is needed to understand if this is the same issue as above, just for Apple provided apps, or if there's some other mechanism that is blocking the DAL plugin from running. See a workaround below.
TODO: Which versions of macOS block DAL plugins in which apps?
One option to allow macOS to allow DAL plugins in system apps / codesigned apps is to disable the system integrity protections (SIP) that cause these plugins to fail to load.
This cannot be stressed enough, but while you do not need to fully disable SIP to have DAL plugins start working (which is good), do this at your own risk as it could bring security implications for your entire system. You can read more about the details of SIP here. In case you are doing this on a company device, make sure this is not going against work policy.
To disable the filesystem part of SIP (that blocks the DAL plugins from loading) run the following command in recovery mode (reboot holding Command + R):
csrutil enable --without fs
