Managed Bookmarks Registry String Not Working As Intended

I’m trying to deploy Brave as our school district’s default browser. With that, I need to have control over certain aspects of the browser, like disabling Tor, enabling the Bookmark bar, and adding Managed Bookmarks to the bar. I have used both Brave’s and Google’s resources to try to implement this, and have successfully got other policies working, but the ManagedBookmarks string will not work.

I’ve testing in Chrome to verify that it is correct, and it is, but adding it to the Brave registry does nothing.

Please fix!
