Thanks for the continued guidance and sorry for my delay as I got a bit distracted with another Roon issue.
I’m pleased to report that the extension works! Auto-discovery found my Roon server after a bit of time (maybe it had to do with my other issue that seems to be resolved at the moment).

Thanks for the step by step instructions. It’ll be good to have if I need it later.
