Update Issue?

    notes-app update Mobibase (--body "")

    ==> zsh: unknown file attribute: b

**Big Sur**, **version 0.0.7**

I'm trying to clear a note, but not delete it.  How can this be done?  The docs suggest my command above should do this, but the error is odd and nothing is happening.  Not sure if this is an OS issue.  `notes-app list` works fine.
