Using Appium Desktop's 1.12.1 new 'Actions' feature

Is there doc on how to use this feature? I’m trying to do a long press on and element using the args for my ‘execute’:
command: performTouch
jsonArguments: {“actions”:[{“action”:“longPress”,“options”:{“element”:“DD000000-0000-0000-BB39-000000000000”,“duration”:1000}},{“action”:“wait”,“options”:{“ms”:4000}},{“action”:“release”,“options”:{}}]}

This does not work. Can someone help with the expected syntax? A simple tap example might help?

Thank you,
