How to Prevent Uninstalling Chrome Extension on macOS

There is an extension that I want to make harder to delete or disable on Chrome, how can I go about doing this? I have tried to edit the ExtensionInstallForcelist policy using: defaults write com.google.Chrome ExtensionInstallForcelist -array "blaaajhemilngeeffpbfkdjjoefldkok;https://clients2.google.com/service/update2/crx " but I can still delete or disable the extension. Furthermore, the level is set to "Recommended" instead of "Mandatory". How could I fix this?
