Is there a way to unpublish a message

I am using the api put method for the messages endpoint to update an individual message https://devdocportal.lithium.com/t5/Community-API-v2-Reference/bd-p/restv2docs?section=commv2&collection=messages . Is there a way to unpublish a message. I already tried is_draft : true in the body for the put method and i get a 200 response but the message is still published.
