Shortcuts Events process isn't running - AppleScript fails

I'm trying to use the new Shortcuts for Mac scripting interface on the first Monterey beta.

I'm having trouble running the example AppleScript shown in WWDC21 Meet Shortcuts For Mac (10232):

tell application "Shortcuts Events"
	run the shortcut named "Dummy"
end tell

It doesn't seem to recognise a process called 'Shortcuts Events', and I get this error:

The command-line utility works as expected in terminal.
