Hands free use of Roomies new Voice Control?

My Roomie use case is entirely based on voice activation and I rarely ever open the Roomie app. I run activities with Siri Shortcuts. It sounds like the new V7 voice control depends on the app being open. Is there a way to do it hands free, like using a Siri command? And would that just be redundant to the existing Shortcuts interface? Does the Voice Control provide more or less control than the existing Shortcuts interface?
