I'm trying to setup a policy for a Chrome Extension that supports managed storage. I'm following these steps:
https://www.chromium.org/administrators/configuring-policy-for-extensions/
And running these commands as specified, replacing my username and the plist path:
dscl -u username /Local/Default -mcximport /Computers/local_computer configuration.plist
sudo mcxrefresh -n username
However when I navigate to chrome://policy/, I still see "No policies set" for my extension. What am I doing wrong?
