We’ve updated the Using Hook with Obsidian – Hook page. It now includes a section on Getting hook://file/
URLs. That section contains a (JavaScript) script you can paste in the Hook > Preferences > Scripts tab > Obsidian > Get Address pane
. That would override Hook’s built-in script for Obsidian which returns obsidian://open?
URLs.
The pros/cons of using that are described in that Help page.
