Did you hit this in the Docs open flow?
micasa will call xdg-open (linux)/open (mac)/cmd (windows) when opening a document, but there's nothing that's explicitly opening a text editor.
Looks like it doesn't register `$VISUAL` but does use `$EDITOR` not sure if that is a `xdg-open` behavior though.
I've been a 1password customer for many years, so I'm a bit bummed out about this.
