I've been working with the x-callback-ur scheme to try and send text from Drafts 4 to Editorial, but so far I've only succeeded in creating a blank file.
I've create the following as a Drafts 4 action: editorial://x-callback-url/open?root=new&selection=0
This invokes editorial but it opens with a new, blank file rather than opening the text created in Drafts 4.
What am I doing wrong here?
