Using org-protocol as mentioned here and set up on Windows as mentioned here after opening the URL
org-protocol://roam-ref?template=r&ref=test&title=test in the browser, I am put into an empty Emacs buffer with the file name
I also did
org-roam-protocol-open-ref and it seems it is never called. Any hints on how to further debug this?
Update: This might be solved after reading the upcoming chapter in Zero to Emacs and Org-roam: a step-by-step guide on Windows 10
