Since the Chromium 79 snap, this seems to no longer work.
I have the libwidevinecdm.so from Firefox in ~/snap/chromium/current/.local/lib/, which always worked fine before, but now EME videos all just show warnings and the plugin does not seem to be loaded.
Extracting the libwidevinecdm.so from a Chrome deb and putting it in the same place also does not help.
