Automating iCloudsharing for Things

I use Things as my todo planner and for this I use the iCloud Share Documents option to add files to a specific „to do“.

For this I share the file with myself and use the „create link“. Is there a way to automate this with shortcuts? I do not want to use the action that creates a public link.
I already made a shortcut, where my emailadress is passed to the clipboard, so I do not have to manually insert this in everytime, but it is still a lot of clicking until this is done :wink:
