managed storage for the “Open in Firefox’-extension in Chrome

[Tsja2023]

How do I use managed storage for the “Open in Firefox’-extension in Chrome?
The example given in the Q&A is for a Firefox Plugin.
Having difficulty finding the "Chrome-way" of using the managed storage.

You just need to set a regexp;

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\Software\Policies\Google\Chrome\3rdparty\extensions
\[EXTENSION_ID_IN_CHROME]\policy]
"hosts"="[\"www.google.com\", \"www.bing.com\"]"

Check chrome://policy/ to make sure the policy is applied.

I can't manage to get this to work no matter what I try. I've got plenty of other chrome policies applied successfully.

Wrong path?

Progress! Fixing the path gets me the hosts visible in policy:

but 1) the policy set settings dont seem to show up in settings
2) How do is et the rest of the config options? executable path, etc. Did not see any documentation in the faq https://webextension.org/listing/open-in.html?from=chromium#faq17
